First wave attacks are characterised by the absence of defending players around their goal perimeter. The chance of success is very high, as the throwing player is unhindered in his scoring attempt. Such attacks typically occur after an intercepted pass or a steal, and if the defending team can switch fast to offence. The far left or far right will usually try to run the attack, as they are not as tightly bound in the defence. On a turnover, they immediately sprint forward and receive the ball halfway to the other goal. Thus, these positions are commonly held by quick players. Second wave If the first wave is not successful and some defending players have gained their positions around the zone, the second wave comes into play: the remaining players advance with quick passes to locally outnumber the retreating defenders. If one player manages to step up to the perimeter or catches the ball at this spot, he becomes unstoppable by legal defensive means. From this position, the chance of success is naturally very high. Second wave attacks became much more important with the "fast throw-off" rule. Third wave The time during which the second wave may be successful is very short, as then the defenders closed the gaps around the zone. In the third wave, the attackers use standardised attack patterns usually involving crossing and passing between the back court players who either try to pass the ball through a gap to their pivot, take a jumping shot from the backcourt at the goal, or lure the defence away from a wingman. The third wave evolves into the normal offensive play when all defenders not only reach the zone, but gain their accustomed positions. Some teams then substitute specialised offence players. However, this implies that these players must play in the defence should the opposing team be able to switch quickly to offence. The latter is another benefit for fast playing teams.
If the attacking team does not make sufficient progress (eventually releasing a shot on goal), the referees can call passive play (since 1995, the referee gives an advance warning by holding one hand high, signalling that the attacking team should release a shot soon), turning control over to the other team. A shot on goal or an infringement leading to a yellow card or two-minute penalty will mark the start of a new attack, causing the hand to be taken down; but a shot blocked by the defense or a normal free throw will not. This rule prevents an attacking team from stalling the game indefinitely, as it is difficult to intercept a pass without at the same time conceding dangerous openings towards the goal.
Defensive play Edit The usual formations of the defense are 6–0, when all the defense players line up between the 6-metre (20 ft) and 9-metre (30 ft) lines to form a wall; the 5–1, when one of the players cruises outside the 9-metre (30 ft) perimeter, usually targeting the center forwards while the other 5 line up on the 6-metre (20 ft) line; and the less common 4–2 when there are two such defenders out front. Very fast teams will also try a 3–3 formation which is close to a switching man-to-man style. The formations vary greatly from country to country, and reflect each country's style of play. 6–0 is sometimes known as "flat defense", and all other formations are usually called "offensive defense".
Records
The current worldwide attendance record for seven-a-side handball was set on 6 September 2014, during a neutral venue German league game between HSV Hamburg and the Mannheim-based Rhein-Neckar Lions.[27] The matchup drew 44,189 spectators to Commerzbank Arena in Frankfurt, exceeding the previous record of 36,651 set at Copenhagen's Parken Stadium during the 2011 Danish Cup final.[27]
Penalties
Penalties are given to players, in progressive format, for fouls that require more punishment than just a free-throw. Actions directed mainly at the opponent and not the ball (such as reaching around, holding, pushing, tripping, and jumping into opponent) as well as contact from the side, from behind a player or impeding the opponent's counterattack are all considered illegal and are subject to penalty. Any infraction that prevents a clear scoring opportunity will result in a seven-metre penalty shot.
Typically the referee will give a warning yellow card for an illegal action; but, if the contact was particularly dangerous, like striking the opponent in the head, neck or throat, the referee can forego the warning for an immediate two-minute suspension. Players are warned once before given a yellow card; they risk being red-carded if they draw three yellows.
A red card results in an ejection from the game and a two-minute penalty for the team. A player may receive a red card directly for particularly rough penalties. For instance, any contact from behind during a fast break is now being treated with a red card; as does any deliberate intent to injure opponents. A red-carded player has to leave the playing area completely. A player who is disqualified may be substituted with another player after the two-minute penalty is served. A coach or official can also be penalized progressively. Any coach or official who receives a two-minute suspension will have to pull out one of their players for two minutes; however, the player is not the one punished, and can be substituted in again, as the penalty consists of the team playing with one fewer player than the opposing team.
After referees award the ball to the opponents for whatever reason, the player currently in possession of the ball has to lay it down quickly, or risk a two-minute suspension. Also, gesticulating or verbally questioning the referee's order, as well as arguing with the officials' decisions, will normally risk a yellow card. If the suspended player protests further, does not walk straight off the court to the bench, or if the referee deems the tempo deliberately slow, that player risks a double yellow card. Illegal substitution (outside of the dedicated area, or if the replacement player enters too early) is prohibited; if they do, they risk a yellow card.
Gameplay
Players are typically referred to by the positions they are playing. The positions are always denoted from the view of the respective goalkeeper, so that a defender on the right opposes an attacker on the left. However, not all of the following positions may be occupied depending on the formation or potential suspensions.
Offense Edit Left and right wingman. These typically are fast players who excel at ball control and wide jumps from the outside of the goal perimeter in order to get into a better shooting angle at the goal. Teams usually try to occupy the left position with a right-handed player and vice versa. Left and right backcourt. Goal attempts by these players are typically made by jumping high and shooting over the defenders. Thus, it is usually advantageous to have tall players with a powerful shot for these positions. Centre backcourt. A player with experience is preferred on this position who acts as playmaker and the handball equivalent of a basketball point guard. Pivot (left and right, if applicable). This player tends to intermingle with the defence, setting picks and attempting to disrupt the defence's formation. This position requires the least jumping skills; but ball control and physical strength are advantages. Sometimes, the offense uses formations with two pivot players.
Defense Edit There are many variations in defensive formations. Usually, they are described as n:m formations, where n is the number of players defending at the goal line and m the number of players defending more offensive. Exceptions are the 3:2:1 defense and n+m formation (e.g. 5+1), where m players defend some offensive player in man coverage (instead of the usual zone coverage).
Far left and far right. The opponents of the wingmen. Half left and half right. The opponents of the left and right backcourts. Back center (left and right). Opponent of the pivot. Front center. Opponent of the center backcourt, may also be set against another specific backcourt player. Offensive play Edit Attacks are played with all court players on the side of the defenders. Depending on the speed of the attack, one distinguishes between three attack waves with a decreasing chance of success:
Ball
The ball is spherical and must be made either of leather or a synthetic material. It is not allowed to have a shiny or slippery surface. As the ball is intended to be operated by a single hand, its official sizes vary depending on age and gender of the participating teams.
Awarded throws Edit The referees may award a special throw to a team. This usually happens after certain events such as scored goals, off-court balls, turnovers and timeouts. All of these special throws require the thrower to obtain a certain position, and pose restrictions on the positions of all other players. Sometimes the execution must wait for a whistle blow by the referee.
Throw-off A throw-off takes place from the center of the court. The thrower must touch the middle line with one foot, and all the other offensive players must stay in their half until the referee restarts the game. The defending players must keep a distance of at least three metres from the thrower until the ball leaves his hand. A throw-off occurs at the beginning of each period and after the opposing team scores a goal. It must be cleared by the referees. Modern handball introduced the "fast throw-off" concept; i.e., the play will be immediately restarted by the referees as soon as the executing team fulfills its requirements. Many teams leverage this rule to score easy goals before the opposition has time to form a stable defense line. Throw-in The team which did not touch the ball last is awarded a throw-in when the ball fully crosses the side line or touches the ceiling. If the ball crosses the outer goal line, a throw-in is awarded only if the defending court players touched the ball last. Execution requires the thrower to place one foot on the nearest outer line to the cause. All defending players must keep a distance of three metres (9.8 ft). However, they are allowed to stand immediately outside their own goal area even when the distance is less than three metres. Goalkeeper-throw If the ball crosses the outer goal line without interference from the defending team or when deflected by the defending team's goalkeeper, or when the attacking team violates the D-zone as described above, a goalkeeper-throw is awarded to the defending team. This is the most common turnover. The goalkeeper resumes the play with a throw from anywhere within the goal area. Free-throw A free-throw restarts the play after an interruption by the referees. It takes places from the spot where the interruption was caused, as long as this spot is outside of the free-throw line of the opposing team. In the latter case, the throw is deferred to the nearest spot on the free-throw line. Free-throws are the equivalent to free-kicks in association football; however, conceding them is typically not seen as poor sportsmanship for the defending side, and in itself, they carry no major disadvantages. (In particular, being awarded a free throw while being on warning for passive play will not reset the warning, whereas a shot on goal will.) The thrower may take a direct attempt for a goal which, however, is rarely feasible if the defending team has organised a defense. However, if a free throw is awarded and the half or game ends, a direct throw at the goal is typically attempted, which occasionally goes in.
Seven-metre throw A seven-metre throw is awarded when a clear chance of scoring is illegally prevented anywhere on the court by an opposing team player, official, or spectator. It is awarded also when the referees have interrupted a legitimate scoring chance for any reason. The thrower steps with one foot behind the 7-metre line with only the defending goalkeeper between him and the goal. The goalkeeper must keep a distance of 3 metres away, which is marked by a short tick on the floor. All other players must remain behind the free-throw line until execution and the defending court players must keep a distance of three metres. The thrower must await the whistle blow of the referee. A seven-metre throw is the equivalent to a penalty kick in association football; however, it is far more common and typically occurs several times in a single game. It is thus tactically similar to free throw percentage in basketball and teams will try to have their best seven metre throwers execute those throws.
A standard match has two 30-minute halves with a 10- or 15-minute (major Championships/Olympics) halftime intermission. At half-time, teams switch sides of the court as well as benches. For youths, the length of the halves is reduced—25 minutes at ages 12 to 15, and 20 minutes at ages 8 to 11; though national federations of some countries may differ in their implementation from the official guidelines.[15]
If a decision must be reached in a particular match (e.g., in a tournament) and it ends in a draw after regular time, there are at maximum two overtimes, each consisting of two straight 5-minute periods with a one-minute break in between. Should these not decide the game either, the winning team is determined in a penalty shootout (best-of-five rounds; if still tied, extra rounds are added until one team wins).
The referees may call timeout according to their sole discretion; typical reasons are injuries, suspensions, or court cleaning. Penalty throws should trigger a timeout only for lengthy delays, such as a change of the goalkeeper.
Since 2012, teams can call 3 team timeouts per game (up to two per half), which last one minute each. This right may only be invoked by the team in possession of the ball. Team representatives must show a green card marked with a black T on the timekeeper's desk. The timekeeper then immediately interrupts the game by sounding an acoustic signal to stop the clock. Before 2012, teams were allowed only one timeout per half. For the purpose of calling timeouts, overtime and shootouts are extensions of the second half.
Referees Edit A handball match is adjudicated by two equal referees. Some national bodies allow games with only a single referee in special cases like illness on short notice. Should the referees disagree on any occasion, a decision is made on mutual agreement during a short timeout; or, in case of punishments, the more severe of the two comes into effect. The referees are obliged to make their decisions "on the basis of their observations of facts".[16] Their judgements are final and can be appealed against only if not in compliance with the rules.
The referees position themselves in such a way that the team players are confined between them. They stand diagonally aligned so that each can observe one side line. Depending on their positions, one is called court referee and the other goal referee. These positions automatically switch on ball turnover. They physically exchange their positions approximately every 10 minutes (long exchange), and change sides every five minutes (short exchange).
The IHF defines 18 hand signals for quick visual communication with players and officials. The signal for warning is accompanied by a yellow card.[17] A disqualification for the game is indicated by a red card,[18] followed by a blue card if the disqualification will be accompanied by a report.[19] The referees also use whistle blows to indicate infractions or to restart the play.
The referees are supported by a scorekeeper and a timekeeper who attend to formal things such as keeping track of goals and suspensions, or starting and stopping the clock, respectively. They also keep an eye on the benches and notify the referees on substitution errors. Their desk is located between the two substitution areas.
Team players, substitutes, and officials Edit Each team consists of seven players on court and seven substitute players on the bench. One player on the court must be the designated goalkeeper, differing in his clothing from the rest of the court players. Substitution of players can be done in any number and at any time during game play. An exchange takes place over the substitution line. A prior notification of the referees is not necessary.
Some national bodies, such as the Deutsche Handball Bund (DHB, "German Handball Federation"), allow substitution in junior teams only when in ball possession or during timeouts. This restriction is intended to prevent early specialization of players to offence or defence.
Court players Edit Court players are allowed to touch the ball with any part of their bodies above and including the knee. As in several other team sports, a distinction is made between catching and dribbling. A player who is in possession of the ball may stand stationary for only three seconds, and may take only three steps. They must then either shoot, pass, or dribble the ball. Taking more than three steps at any time is considered travelling, and results in a turnover. A player may dribble as many times as they want (though, since passing is faster, it is the preferred method of attack), as long as during each dribble the hand contacts only the top of the ball. Therefore, carrying is completely prohibited, and results in a turnover. After the dribble is picked up, the player has the right to another three seconds or three steps. The ball must then be passed or shot, as further holding or dribbling will result in a double dribble turnover and a free throw for the other team. Other offensive infractions that result in a turnover include charging and setting an illegal screen. Carrying the ball into the six-metre zone results either in ball possession by the goalkeeper (by attacker) or turnover (by defender).
Goalkeeper Edit Only the goalkeepers are allowed to move freely within the goal perimeter, although they may not cross the goal perimeter line while carrying or dribbling the ball. Within the zone, they are allowed to touch the ball with all parts of their bodies, including their feet, with a defensive aim (for other actions, they are subject to the same restrictions as the court players). The goalkeepers may participate in the normal play of their teammates. They may be substituted by a regular court player if their team elects to use this scheme in order to outnumber the defending players. Prior to 2015, this court player became the designated goalkeeper on the court and had to wear some vest or bib to be identified as such. That vest had to be the same colour as the goalkeeper's shirt to avoid confusion. A rule change meant to make the game more offensive now allows any player to substitute with the goalkeeper. The new rule resembles the one used in ice hockey. This rule was first used in the women's world championship in December 2015 and has since been used by the men's European championship in January 2016 and by both genders in the Olympic tournament in 2016. This rule change has led to a drastic increase of empty net goals.[citation needed]
If either goalkeeper deflects the ball over the outer goal line, their team stays in possession of the ball, in contrast to other sports like football. The goalkeeper resumes the play with a throw from within the zone ("goalkeeper throw"). In a penalty shot, throwing the ball against the head of a goalkeeper who is not moving risks a direct disqualification ("red card").
Outside of own D-zone, the goalkeeper is treated as an ordinary court player, and has to follow court players' rules; holding or tackling an opponent player outside the area risks a direct disqualification.[clarification needed] The goalkeeper may not return to the area with the ball. Passing to one's own goalkeeper results in a turnover.
Team officials Edit Each team is allowed to have a maximum of four team officials seated on the benches. An official is anybody who is neither player nor substitute. One official must be the designated representative who is usually the team manager. Since 2012, representatives can call up to 3 team timeouts (up to twice per half), and may address the scorekeeper, timekeeper, and referees (before that, it was once per half); overtime and shootouts are considered extensions of the second half. Other officials typically include physicians or managers. No official is allowed to enter the playing court without the permission of the referees.
Handball (also known as team handball, European handball or Olympic handball)[3] is a team sport in which two teams of seven players each (six outcourt players and a goalkeeper) pass a ball using their hands with the aim of throwing it into the goal of the other team. A standard match consists of two periods of 30 minutes, and the team that scores more goals wins.
Modern handball is played on a court of 40 by 20 metres (131 by 66 ft), with a goal in the middle of each end. The goals are surrounded by a 6-metre (20 ft) zone where only the defending goalkeeper is allowed; goals must be scored by throwing the ball from outside the zone or while "diving" into it. The sport is usually played indoors, but outdoor variants exist in the forms of field handball, Czech handball (which were more common in the past) and beach handball. The game is fast and high-scoring: professional teams now typically score between 20 and 35 goals each, though lower scores were not uncommon until a few decades ago. Body contact is permitted for the defenders trying to stop the attackers from approaching the goal. No protective equipment is mandated, but players may wear soft protective bands, pads and mouth guards.[4]
The game was codified at the end of the 19th century in Denmark. The modern set of rules was published in 1917 by Karl Schelenz, Max Heiser, and Erich Konigh,[5] on 29 October in Berlin, which day is seen as the date of birth of the sport.[1][6] The rules have had several revisions since. The first official handball match was played in 1917 in Germany.[1] Karl Schelenz modified the rules in 1919.[5] The first international games were played (under these rules) with men in 1925 (between Germany and Belgium) and with women in 1930 (between Germany and Austria).[7]
Men's handball was first played at the Olympics in the 1936 Summer Olympics in Berlin outdoors, and the next time at the 1972 Summer Olympics in Munich indoors; handball has been an Olympic sport since then. Women's handball was added at the 1976 Summer Olympics.[8]
The International Handball Federation was formed in 1946 and, as of 2016, has 197 member federations.[9] The sport is most popular in Europe, and European countries have won all medals but one in the men's world championships since 1938. In the women's world championships, only two non-European countries have won the title: South Korea and Brazil. The game also enjoys popularity in East Asia, North Africa and parts of South America.
Rules
Two teams of seven players (six court players plus one goalkeeper) take the court and attempt to score points by putting the game ball into the opposing team's goal. In handling the ball, players are subject to the following restrictions:
After receiving the ball, players can pass, keep possession, or shoot the ball. Players are not allowed to touch the ball with their feet, the goalkeeper is the only one allowed to use their feet but only within the goal area If possessing the ball, players must dribble (similar to a basketball dribble), or can take up to three steps for up to three seconds at a time without dribbling. No attacking or defending players other than the defending goalkeeper are allowed to touch the floor of the goal area (within six metres of the goal). A shot or pass in the goal area is valid if completed before touching the floor. Goalkeepers are allowed outside the goal area, but are not allowed to cross the goal area boundary with the ball in their hands. The ball may not be passed back to the goalkeeper when they are positioned in the goal area. Notable scoring opportunities can occur when attacking players jump into the goal area. For example, an attacking player may catch a pass while launching inside the goal area, and then shoot or pass before touching the floor. Doubling occurs when a diving attacking player passes to another diving teammate
Handball is played on a court 40 by 20 metres (131 ft 3 in × 65 ft 7 in), with a goal in the centre of each end. The goals are surrounded by a near-semicircular area, called the zone or the crease, defined by a line six metres from the goal. A dashed near-semicircular line nine metres from the goal marks the free-throw line. Each line on the court is part of the area it encompasses; the centre line belongs to both halves at the same time.
Goals Edit The goals are two metres high and three metres wide. They must be securely bolted either to the floor or the wall behind.
The goal posts and the crossbar must be made out of the same material (e.g., wood or aluminium) and feature a quadratic cross section with sides of 8 cm (3 in). The three sides of the beams visible from the playing court must be painted alternatingly in two contrasting colors which both have to contrast against the background. The colors on both goals must be the same.
Each goal must feature a net. This must be fastened in such a way that a ball thrown into the goal does not leave or pass the goal under normal circumstances. If necessary, a second net may be clasped to the back of the net on the inside.
Crease Edit The goals are surrounded by the crease, also called the zone. This area is delineated by two quarter circles with a radius of six metres around the far corners of each goal post and a connecting line parallel to the goal line. Only the defending goalkeeper is allowed inside this zone. However, court players may catch and touch the ball in the air within it as long as the player starts their jump outside the zone and releases the ball before they land (landing inside the perimeter is allowed in this case as long as the ball has been released).
If a player without the ball contacts the ground inside the goal perimeter, or the line surrounding the perimeter, they must take the most direct path out of it. However, should a player cross the zone in an attempt to gain an advantage (e.g., better position) their team cedes the ball. Similarly, violation of the zone by a defending player is penalized only if they do so in order to gain an advantage in defending.
Substitution area Edit Outside of one long edge of the court to both sides of the middle line are the substitution areas for each team. Team officials, substitutes, and suspended players must wait within this area. A team's area is the same side as the goal the team is defending; during halftime, substitution areas are swapped. Any player entering or leaving the play must cross the substitution line which is part of the side line and extends 4.5 metres (15 ft) from the middle line to the team's side.
Computer programming is the process of performing a particular computation (or more generally, accomplishing a specific computing result), usually by designing and building an executable computer program. Programming involves tasks such as analysis, generating algorithms, profiling algorithms' accuracy and resource consumption, and the implementation of algorithms (usually in a chosen programming language, commonly referred to as coding).[1][2] The source code of a program is written in one or more languages that are intelligible to programmers, rather than machine code, which is directly executed by the central processing unit. The purpose of programming is to find a sequence of instructions that will automate the performance of a task (which can be as complex as an operating system) on a computer, often for solving a given problem. Proficient programming thus usually requires expertise in several different subjects, including knowledge of the application domain, specialized algorithms, and formal logic.
Tasks accompanying and related to programming include testing, debugging, source code maintenance, implementation of build systems, and management of derived artifacts, such as the machine code of computer programs. These might be considered part of the programming process, but often the term software development is used for this larger process with the term programming, implementation, or coding reserved for the actual writing of code. Software engineering combines engineering techniques with software development practices. Reverse engineering is a related process used by designers, analysts, and programmers to understand an existing program and re-implement its function.[3]
The human brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem and the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making decisions as to the instructions sent to the rest of the body. The brain is contained in, and protected by, the skull bones of the head.
The cerebrum, the largest part of the human brain, consists of two cerebral hemispheres. Each hemisphere has an inner core composed of white matter, and an outer surface – the cerebral cortex – composed of grey matter. The cortex has an outer layer, the neocortex, and an inner allocortex. The neocortex is made up of six neuronal layers, while the allocortex has three or four. Each hemisphere is conventionally divided into four lobes – the frontal, temporal, parietal, and occipital lobes. The frontal lobe is associated with executive functions including self-control, planning, reasoning, and abstract thought, while the occipital lobe is dedicated to vision. Within each lobe, cortical areas are associated with specific functions, such as the sensory, motor and association regions. Although the left and right hemispheres are broadly similar in shape and function, some functions are associated with one side, such as language in the left and visual-spatial ability in the right. The hemispheres are connected by commissural nerve tracts, the largest being the corpus callosum.
The cerebrum is connected by the brainstem to the spinal cord. The brainstem consists of the midbrain, the pons, and the medulla oblongata. The cerebellum is connected to the brainstem by three pairs of nerve tracts called cerebellar peduncles. Within the cerebrum is the ventricular system, consisting of four interconnected ventricles in which cerebrospinal fluid is produced and circulated. Underneath the cerebral cortex are several important structures, including the thalamus, the epithalamus, the pineal gland, the hypothalamus, the pituitary gland, and the subthalamus; the limbic structures, including the amygdala and the hippocampus; the claustrum, the various nuclei of the basal ganglia; the basal forebrain structures, and the three circumventricular organs. The cells of the brain include neurons and supportive glial cells. There are more than 86 billion neurons in the brain, and a more or less equal number of other cells. Brain activity is made possible by the interconnections of neurons and their release of neurotransmitters in response to nerve impulses. Neurons connect to form neural pathways, neural circuits, and elaborate network systems. The whole circuitry is driven by the process of neurotransmission.
The brain is protected by the skull, suspended in cerebrospinal fluid, and isolated from the bloodstream by the blood–brain barrier. However, the brain is still susceptible to damage, disease, and infection. Damage can be caused by trauma, or a loss of blood supply known as a stroke. The brain is susceptible to degenerative disorders, such as Parkinson's disease, dementias including Alzheimer's disease, and multiple sclerosis. Psychiatric conditions, including schizophrenia and clinical depression, are thought to be associated with brain dysfunctions. The brain can also be the site of tumours, both benign and malignant; these mostly originate from other sites in the body.
The study of the anatomy of the brain is neuroanatomy, while the study of its function is neuroscience. Numerous techniques are used to study the brain. Specimens from other animals, which may be examined microscopically, have traditionally provided much information. Medical imaging technologies such as functional neuroimaging, and electroencephalography (EEG) recordings are important in studying the brain. The medical history of people with brain injury has provided insight into the function of each part of the brain. Brain research has evolved over time, with philosophical, experimental, and theoretical phases. An emerging phase may be to simulate brain activity.[2]
In culture, the philosophy of mind has for centuries attempted to address the question of the nature of consciousness and the mind–body problem. The pseudoscience of phrenology attempted to localise personality attributes to regions of the cortex in the 19th century. In science fiction, brain transplants are imagined in tales such as the 1942 Donovan's Brain.
The Peloponnesian War (431–404 BC) was an ancient Greek war fought between Athens and Sparta and their respective allies for the hegemony of the Greek world. The war remained undecided for a long time until the decisive intervention of the Persian Empire in support of Sparta. Led by Lysander, the Spartan fleet built with Persian subsidies finally defeated Athens and started a period of Spartan hegemony over Greece.
Historians have traditionally divided the war into three phases. The first phase (431–421 BC) was named the Ten Years War, or the Archidamian War, after the Spartan king Archidamus II, who launched several invasions of Attica with the full hoplite army of the Peloponnesian League, the alliance network dominated by Sparta. However, the Long Walls of Athens rendered this strategy ineffective, while the superior navy of the Delian League (Athens' alliance) raided the Peloponnesian coast to trigger rebellions within Sparta. The precarious Peace of Nicias was signed in 421 BC and lasted until 413 BC. Several proxy battles took place during this period, notably the battle of Mantinea in 418 BC, won by Sparta against an ad-hoc alliance of Elis, Mantinea (both former Spartan allies), Argos and Athens. The main event was nevertheless the Sicilian Expedition between 415 and 413 BC, during which Athens lost almost all its navy in the attempted capture of Syracuse, an ally in Sparta.
The Sicilian disaster prompted the third phase of the war (413–404 BC), named the Decelean War, or the Ionian War, when the Persian Empire supported Sparta in order to recover the suzerainty of the Greek cities of Asia Minor, incorporated into the Delian League at the end of the Persian Wars. With Persian money, Sparta built a massive fleet under the leadership of Lysander, who won a streak of decisive victories in the Aegean Sea, notably at Aegospotamos in 405 BC. Athens capitulated the following year and lost all its empire; Lysander imposed puppet oligarchies on the former members of the Delian League, including Athens, where the regime was known as the Thirty Tyrants. The Peloponnesian War was followed ten years later by the Corinthian War (394–386 BC), which, although it ended inconclusively, helped Athens regain its independence from Sparta.
The Peloponnesian War reshaped the ancient Greek world. On the level of international relations, Athens, the strongest city-state in Greece prior to the war's beginning, was reduced to a state of near-complete subjection, while Sparta became established as the leading power of Greece. The economic costs of the war were felt all across Greece; poverty became widespread in the Peloponnese, while Athens was completely devastated, and never regained its pre-war prosperity.[2][3] The war also wrought subtler changes to Greek society; the conflict between democratic Athens and oligarchic Sparta, each of which supported friendly political factions within other states, made war a common occurrence in the Greek world. Ancient Greek warfare, meanwhile, originally a limited and formalized form of conflict, was transformed into an all-out struggle between city-states, complete with atrocities on a large scale. Shattering religious and cultural taboos, devastating vast swathes of countryside, and destroying whole cities, the Peloponnesian War marked the dramatic end to the fifth century BC and the golden age of Greece.[4]
The historicity of the Trojan War, including whether it occurred at all and where Troy was located if it ever existed, is still subject to debate. Most classical Greeks thought that the war was a historical event, but many believed that the Homeric poems had exaggerated the events to suit the demands of poetry. For instance, the historian Thucydides, who is known for being critical, considers it a true event but doubts that 1,186 ships were sent to Troy. Euripides started changing Greek myths at will, including those of the Trojan War. Near AD 100, Dio Chrysostom argued that while the war was historical, it ended with the Trojans winning, and the Greeks attempted to hide that fact.[220] Around 1870 it was generally agreed in Western Europe that the Trojan War had never happened and Troy never existed.[221] Then Heinrich Schliemann popularized his excavations at Hisarlik, Canakkale, which he and others believed to be Troy, and of the Mycenaean cities of Greece. Today many scholars agree that the Trojan War is based on a historical core of a Greek expedition against the city of Troy, but few would argue that the Homeric poems faithfully represent the actual events of the war.
In November 2001, geologist John C. Kraft and classicist John V. Luce presented the results of investigations into the geology of the region that had started in 1977.[222][223][224] The geologists compared the present geology with the landscapes and coastal features described in the Iliad and other classical sources, notably Strabo's Geographica. Their conclusion was that there is regularly a consistency between the location of Troy as identified by Schliemann (and other locations such as the Greek camp), the geological evidence, and descriptions of the topography and accounts of the battle in the Iliad, although of course this could be a coincidence.
In the twentieth century scholars have attempted to draw conclusions based on Hittite and Egyptian texts that date to the time of the Trojan War. While they give a general description of the political situation in the region at the time, their information on whether this particular conflict took place is limited. Andrew Dalby notes that while the Trojan War most likely did take place in some form and is therefore grounded in history, its true nature is unknown.[225] The Tawagalawa letter mentions a kingdom of Ahhiyawa (Achaea, or Greece) that lies beyond the sea (that would be the Aegean) and controls Milliwanda, which is identified with Miletus. Also mentioned in this and other letters is the Assuwa confederation made of 22 cities and countries which included the city of Wilusa (Ilios or Ilium). The Milawata letter implies this city lies on the north of the Assuwa confederation, beyond the Seha river. While the identification of Wilusa with Ilium (that is, Troy) is always controversial, in the 1990s it gained majority acceptance. In the Alaksandu treaty (c. 1280 BC) the king of the city is named Alaksandu, and Paris's name in the Iliad (among other works) is Alexander. The Tawagalawa letter (dated c. 1250 BC) which is addressed to the king of Ahhiyawa actually says: "Now as we have come to an agreement on Wilusa over which we went to war ..."[full citation needed]
Formerly under the Hittites, the Assuwa confederation defected after the battle of Kadesh between Egypt and the Hittites (c. 1274 BC). In 1230 BC Hittite king Tudhaliya IV (c. 1240–1210 BC) campaigned against this federation. Under Arnuwanda III (c. 1210–1205 BC) the Hittites were forced to abandon the lands they controlled in the coast of the Aegean. It is possible that the Trojan War was a conflict between the king of Ahhiyawa and the Assuwa confederation. This view has been supported in that the entire war includes the landing in Mysia (and Telephus' wounding), Achilles's campaigns in the North Aegean and Telamonian Ajax's campaigns in Thrace and Phrygia. Most of these regions were part of Assuwa.[70][226] That most Achaean heroes did not return to their homes and founded colonies elsewhere was interpreted by Thucydides as being due to their long absence.[227] Nowadays the interpretation followed by most scholars is that the Achaean leaders driven out of their lands by the turmoil at the end of the Mycenaean era preferred to claim descent from exiles of the Trojan War.[228]
The history of Greece encompasses the history of the territory of the modern nation-state of Greece as well as that of the Greek people and the areas they inhabited and ruled historically. The scope of Greek habitation and rule has varied throughout the ages and as a result, the history of Greece is similarly elastic in what it includes. Generally, the history of Greece is divided into the following periods:
Paleolithic Greece starting c. 3.3 million years ago and ending in 13,000 BC. Significant geomorphological and climatic changes were noted in the modern Greek area which were definitive for the fauna and flora as well as the survival of the Homo sapiens in the region. Mesolithic Greece starting in 13,000 BC and ending in 7000 BC, it was a period of long and slow development of the primitive human "proto-communities". Neolithic Greece; covering a period beginning with the establishment of agricultural societies in 7000 BC and ending in c. 3200 – c. 3100 BC. It was a vital part of the early history of Greece because it was the base for the early Bronze Age civilizations. The first organized communities were developed and basic art became more advanced. Ancient Greece usually encompasses Greek antiquity, while part of the region's late prehistory (Late Bronze Age) is also considered part of it:
Bronze Age (Cycladic culture, Minoan and Helladic); chronology covering a period beginning with the transition to a metal-based economy in 3200/3100 BC during the Eutresis culture and Korakou culture, Cycladic culture with its special figurines, Europe's first real civilization (Minoan civilization), Tiryns culture, to the rise and fall of the Mycenaean Greek palaces in the Late Bronze Age collapse. Spans roughly five centuries (1600–1100 BC). Greek Dark Ages (or Iron Age, Homeric Age), 1100–800 BC Archaic period, 800–490 BC Classical period 490–323 BC Hellenistic period, 323–146 BC Roman Greece; covering a period from the Roman conquest of Greece in 146 BC – 324 AD Byzantine Greece; covering a period from the establishment of the capital city of Byzantium, Constantinople, in 324 until the fall of Constantinople in 1453 Frankish/Latin Greece; (including the Venetian possessions) covering a period from the Fourth Crusade (1204) to 1797, year of disestablishment of the Venetian Republic Ottoman Greece; covering the period from 1453 until the Greek Revolution of 1821 Modern Greece; covering the period from 1821 to present At its cultural and geographical peak, Greek civilization spread from Egypt all the way to the Hindu Kush mountains in Afghanistan. Since then, Greek minorities have remained in former Greek territories (e.g. Turkey, Albania, Italy, Libya, Levant, Armenia, Georgia) and Greek emigrants have assimilated into differing societies across the globe (e.g. North America, Australia, Northern Europe, South Africa). At present, most Greeks live in the modern states of Greece (independent since 1821) and cyprus
