Ancient Greece

The term ancient Greece refers to the period of Greek history lasting from the Greek Dark Ages ca. 1100 BC and the Dorian invasion, to 146 BC and the Roman conquest of Greece after the battle of Corinth. It is generally considered to be the seminal culture which provided the foundation of Western civilization. Greek culture had a powerful influence on the Roman Empire, which carried a version of it to many parts of Europe. The civilization of the ancient Greeks has been immensely influential on the language, politics, educational systems, philosophy, science, and arts, giving rise to the Renaissance in Western Europe and again resurgent during various neo-Classical revivals in 18th and 19th century Europe and the Americas.

Chronology

Chronology
There are no fixed or universally agreed upon dates for the beginning or the end of the ancient Greek period. In common usage it can refer to all Greek history before the Roman conquest, but historians use the term more precisely. The Greek-speaking Mycenaean civilization that collapsed about 1150 BC and which preceded the classical Greek culture is generally excluded from the ancient Greek era. Some historians took the date of the first recorded Olympic Games in 776 BC as the beginning of the ancient Greek period. Between the end of the Mycenaean period and the first Olympics, there is a period known as the Greek Dark Ages, because there are no written records, and few archaeological remnants. This period is now often included in the term Ancient Greece.
The end of the ancient Greek period was traditionally seen as the death of Alexander the Great in 323 BC, which was seen to begin the Hellenistic period. However, ancient Greece is often taken to include the following period, until to the Roman conquest of 146 BC. Some writers treat the ancient Greek civilization as a continuum running until the advent of Christianity in the 3rd century; this, however, is unconventional.
The ancient Greek period is subdivided into four periods on a pragmatic basis of pottery styles and political events. The Greek Dark Ages (c.1100-c.750 BC) features the use of geometric designs on pottery; it is followed by the Archaic period (c.750-c.480 BC), in which artists made larger free-standing sculptures in stiff, hieratic poses with the dreamlike 'archaic smile'. The Archaic period is often taken to end with the overthrow of the last tyrant of Athens in 510 BC. The Classical period (c.500-323 BC) is characterised by a style which was considered by later observers to be exemplary (i.e. 'classical') - for instance the Parthenon. The death of Alexander in 323 BC is used to mark the beginning of the Hellenistic period, when Greek culture and power expanded into the near and middle east; a period which finishes with the Roman conquest of 146 BC.

Prehistoric and Bronze Age civilization

Helladic period
The tribes who would become the Greeks are believed to have migrated southward into the Balkan peninsula in several waves beginning in the Middle Bronze Age (roughly 2000 BC).[1] The Proto-Greek language would date to the period just preceding these migrations, either to the late 3rd millennium BC, or to the 17th century BC at the latest. The Bronze Age civilization of the proto-Greeks is generally referred to as Helladic and preceded what is known as "Ancient Greece".
The so-called Mycenaean civilization culminated in this period, which features in the famous epics of Homer, the Iliad and the Odyssey. For reasons which are unknown, this culture collapsed spectacularly around 1150 BC, with cities being sacked and a massive depopulation. This Bronze Age collapse approximately coincides with the apparent arrival of the last group of proto-Greeks into Greece proper, the Dorians. The two events have traditionally been causally linked, but this is by no means certain. With the Bronze Age collapse, Greece entered into a period of obscurity or 'dark age'

Classical Greece

5th century
Main articles: Greco-Persian Wars and Peloponnesian War
Athens and Sparta would soon have to become allies in the face of the largest external threat ancient Greece would see until the Roman conquest. After suppressing the Ionian Revolt, a rebellion of the Greek cities of Ionia, Darius I of Persia, King of Kings of the Achaemenid Empire, decided to subjugate Greece. His invasion in 490 BC was ended by the heroic Athenian victory at the Battle of Marathon under Miltiades the Younger. Xerxes I of Persia, son and successor of Darius I, attempted his own invasion 10 years later, but was, despite his overwhelmingly large army, defeated after the famous rearguard action at Thermopylae, and victories for the allied Greeks at the Battles of Salamis and Plataea. The Greco-Persian Wars continued until 449 BC, led by the Athenians and their Delian League, during which time the Macedon, Thrace, the Aegean Islands and Ionia were all liberated from Persian influence.

Delian League ("Athenian Empire"), immediately before the Peloponnesian War in 431 BC.
The now dominant position of the maritime Athenian 'Empire' threatened Sparta and the Peloponnesian League of mainland Greek cities. Inevitably, this led to conflict, resulting in the Peloponnesian War (431-404 BC). Though effectively a stalemate for the vast majority of its length, Athens suffered a number of setbacks during the war. A great plague in 430 BC, followed by the Sicilian Expedition, a disastrous military expedition to Sicily, severely weakened Athens. Sparta was able to ferment rebellion amongst Athens's allies, further reducing the Athenian ability to wage war. The decisive moment came in 405 BC when Sparta cut off the grain supply to Athens from the Hellespont. Forced to attack, the crippled Athenian fleet was decisively defeated by the Spartans under the command of Lysander at Aegospotami. In 404 BC Athens sued for peace, and Sparta dictated a predictably stern settlement: Athens lost her city walls (including the Long Walls), her fleet, and all of her overseas possessions.

4th century
Greece thus entered the 4th century under a Spartan hegemony, but it was clear from the start that this was weak. A demographic crisis meant Sparta was overstretched, and by 395 BC Athens, Argos, Thebes, and Corinth felt able to challenge Spartan dominance, resulting in the Corinthian War (395-387 BC). Another war of stalemates, it ended with the status quo restored, after the threat of Persian intervention on behalf of the Spartans.
The Spartan hegemony lasted another 16 years, until, when attempting to impose their will on the Thebans, the Spartans suffered a decisive defeat at Leuctra (371 BC). The brilliant Theban general Epaminondas then led Theban troops into the Peloponnese, whereupon other city-states defected from the Spartan cause. The Thebans were thus able to march into Messenia and free the population. Deprived of land and its serfs, Sparta declined to a second-rank power. The Theban hegemony thus established was short-lived; at the battle of Mantinea in 362 BC, Thebes lost her key leader, Epaminondas, and great loss of manpower, even though they were victorious in battle. In fact such were the losses to all the great city-states at Mantinea that none could establish dominance in the aftermath.
The weakened state of the heartland of Greece coincided with the rising power of Macedon, led by Philip II. In twenty years, Philip had unified his kingdom, expanded it north and west at the expense of Illyrian tribes, and then conquered Thessaly and Thrace. His success was partly due to his innovative reforms to the army. Phillip intervened repeatedly in the affairs of the southern city-states, culminating in his invasion of 338 BC. Decisively defeating an allied army of Thebes and Athens at the Battle of Chaeronea, he became de facto hegemon of all of Greece. He compelled the majority of the city-states to join the League of Corinth, allying them to him, and preventing them from warring with each other. Philip then entered into war against the Achemaenid Empire, but was assassinated by Pausanias of Orestis early on in the conflict.
Alexander, son and successor of Philip, continued the war. Alexander defeated Darius III of Persia and completely destroyed the Achaemenid Empire, annexing it to Macedon and earning himself the epithet 'the Great'. When Alexander died in 323 BC, Greek power and influence was at its zenith. However, there had been a fundamental shift away from the fierce independence and classical culture of the poleis - and instead towards the developing Hellenistic culture.
