The History of Greece traditionally encompasses the study of the Greek people, the areas they ruled, and the territory now composing the modern state of Greece.

The scope of Greek habitation and rule has varied significantly through the ages, and as a consequence the history of Greece is similarly elastic in what it includes. Each era has its own related sphere of interest.

The first Greeks arrived in Europe some time before 1500 BC, and at its peak, Greek Civilization ruled everything from Greece to Egypt to the Hindu Kush mountains. Since then, large Greek minorities have remained in former Greek territories (e.g., Turkey, Italy, and Libya, Levant, etc.), and Greek Emigrants have assimilated into differing societies across the globe (e.g. North America, Australia, Northern Europe, South Africa etc.). However, today most Greeks live in the modern states of Greece (independent since 1821) and Cyprus (independent since 1960).

Aegean civilization: prehistoric Greece
The earliest civilization to appear around Greece was the Minoan civilization on the Aegean Sea; it lasted approximately from 3000 to 1450 BC . Little specific is known about the Minoans (even the name is a modern appellation, from Minos, the legendary king of Crete). They appear to have been a pre-Indo-European people; their language, known as Eteocretan, may have been written in the undeciphered Linear A script. They were primarily a mercantilist people engaged in overseas trade. Although the causes of their demise are uncertain, they were eventually invaded by the Mycenaeans from mainland Greece.

Mycenaean Greece (Bronze Age)
Mycenaean Greece, also known as Bronze Age Greece, is the Late Helladic Bronze Age civilization of Ancient Greece. It lasted from the arrival of the Greeks in the Aegean around 1600 BC to the collapse of their Bronze Age civilization around 1100 BC. It is the historical setting of the epics of Homer and much other Greek mythology. The Mycenaean period takes its name from the archaeological site Mycenae in the northeastern Argolid, in the Peloponnesos of southern Greece. Athens, Pylos, Thebes, and Tiryns are also important Mycenaean sites.

Mycenaean civilization was dominated by a warrior aristocracy. Around 1400 BC the Mycenaeans extended their control to Crete, center of the Minoan civilization, and adopted a form the Minoan script called Linear A to write their early form of Greek. The Mycenaean era script is called Linear B.

The Mycenaeans buried their nobles in beehive tombs (tholoi), large circular burial chambers with a high vaulted roof and straight entry passage lined with stone. They often buried daggers or some other form of military equipment with the deceased. The nobility were frequently buried with gold masks, tiaras, armour, and jeweled weapons. Mycenaeans were buried in a sitting position, and some of the nobility underwent mummification.

Around 1100 BC the Mycenaean civilization collapsed. Numerous cities were sacked and the region entered what historians see as a dark age. During this period Greece experienced a decline in population and literacy. The Greeks themselves have traditionally blamed this decline on an invasion by another wave of Greek people, the Dorians, although there is scant archeological evidence for this view.

Greek Dark Ages
The Greek Dark Ages (ca. 1200 BC–800 BC) refers to the period of Greek prehistory from the presumed Dorian invasion and end of the Mycenaean civilization in the 11th century BC to the rise of the first Greek city-states in the 9th century BC and the epics of Homer and earliest writings in alphabetic Greek in the 8th century BC.

The collapse of the Mycenaean coincided with the fall of several other large empires in the near east, most notably the Hittite and the Egyptian. The cause may be attributed to an invasion of the sea people wielding iron weapons. When the Dorians came down into Greece they also were equipped with superior iron weapons, easily dispersing the already weakened Mycenaeans. The period that follows these events is collectively known as the Greek Dark Ages.

Archaeology shows a collapse of civilization in the Greek world in this period. The great palaces and cities of the Mycenaeans were destroyed or abandoned. The Greek language ceased to be written. Greek dark age pottery has simple geometric designs and lacks the figurative decoration of Mycenaean ware. The Greeks of the dark age lived in fewer and smaller settlements, suggesting mass depopulation, and foreign goods have not been found at archaeological sites, suggesting minimum international trade. Contact was also lost between foreign powers during this period, yielding little cultural progress or growth of any sort.

Kings ruled throughout this period until eventually they were replaced with an aristocracy, then still later, in some areas, an aristocracy within an aristocracy—an elite of the elite. Warfare shifted from a focus on cavalry to a great emphasis on infantry. Due to its cheapness of production and local availability, iron replaced bronze as the metal of choice in the manufacturing of tools and weapons. Slowly equality grew among the different sects of people, leading to the dethronement of the various Kings and the rise of the family.

Families began to reconstruct their past in attempts to link their bloodlines with heroes from the Trojan War, more specifically Heracles. While most of this was legend, some were sorted by poets of the school of Hesiod. Most of these poems are lost, though, but some famous "storywriters", as they were called, were Hecataeus of Miletus and Acusilaus of Argos.

It is thought that the epics by Homer contain a certain amount of tradition preserved orally during the Dark Ages period. The historical validity of Homer's writings is vigorously disputed; see the article on Troy for a discussion.

At the end of this period of stagnation the Greek civilization was engulfed in a renaissance that spread the Greek world as far as the Black Sea and Spain. Writing was relearned from the Phoenicians, eventually spreading north into Italy and the Gauls.

Ancient Greece
There are no fixed or universally agreed dates for the beginning or the end of the Ancient Greek period. In common usage it refers to all Greek history before the Roman Empire, but historians use the term more precisely. Some writers include the periods of the Minoan and Mycenaean civilizations, while others argue that these civilizations were so different from later Greek cultures that they should be classed separately. Traditionally, the Ancient Greek period was taken to begin with the date of the first Olympic Games in 776 BC, but most historians now extend the term back to about 1000 BC. The traditional date for the end of the Ancient Greek period is the death of Alexander the Great in 323 BC. The following period is classed as Hellenistic. Not everyone treats the Ancient and Hellenic periods as distinct, however, and some writers treat the Ancient Greek civilization as a continuum running until the advent of Christianity in the third century AD.

Ancient Greece is considered by most historians to be the foundational culture of Western Civilization. Greek culture was a powerful influence in the Roman Empire, which carried a version of it to many parts of Europe. Ancient Greek civilization has been immensely influential on the language, politics, educational systems, philosophy, art and architecture of the modern world, particularly during the Renaissance in Western Europe and again during various neo-Classical revivals in 18th and 19th century Europe and The Americas.

The basic unit of politics in Ancient Greece was the polis, sometimes translated as city-state. "Politics" literally means "the things of the polis." Each city was independent, at least in theory. Some cities might be subordinate to others (a colony traditionally deferred to its mother city), some might have had governments wholly dependent upon others (the Thirty Tyrants in Athens was imposed by Sparta following the Peloponnesian War), but the titularly supreme power in each city was located within that city. This meant that when Greece went to war (e.g., against the Persian Empire), it took the form of an alliance going to war. It also gave ample opportunity for wars within Greece between different cities.

The Parthenon is the most famous surviving
building of Ancient Greece and one of the most
famous buildings in the world.

Most of the Greek names known to modern readers flourished in this age. Among the poets, Homer, Hesiod, Pindar, Aeschylus, Sophocles, Euripides, Aristophanes, and Sappho were active. Famous politicians include Themistocles, Pericles, Lysander, Epaminondas, Alcibiades, Philip II of Macedon, and his son Alexander the Great. Plato wrote, as did Aristotle, Heraclitus of Ephesus, Parmenides, Democritus, Herodotus, Thucydides and Xenophon. Almost all of the mathematical knowledge formalized in Euclid's Elements at the beginning of the Hellenistic period was developed in this era.

Two major wars shaped the Ancient Greek world. The Persian Wars (500–448 BC) are recounted in Herodotus's Histories. Ionian Greek cities revolted from the Persian Empire and were supported by some of the mainland cities, eventually led by Athens. (The notable battles of this war include Marathon, Thermopylae, Salamis, and Plataea.)

In order to prosecute the war, and subsequently to defend Greece from further Persian attack, Athens founded the Delian League in 477 BC. Initially, each city in the League would contribute ships and soldiers to a common army, but in time Athens allowed (and then compelled) the smaller cities to contribute funds so that it could supply their quota of ships. Revolution from the League could be punished. Following military reversals against the Persians, the treasury was moved from Delos to Athens, further strengthening the latter's control over the League. The Delian League was eventually referred to pejoratively as the Athenian Empire.

In 458 BC, while the Persian Wars were still ongoing, war broke out between the Delian League and the Peloponnesian League, comprising Sparta and its allies. After some inconclusive fighting, the two sides signed a peace in 447 BC.

That peace, it was stipulated, was to last thirty years: instead it held only until 431 BC, with the onset of the Peloponnesian War. Our main sources concerning this war are Thucydides's History of the Peloponnesian War and Xenophon's Hellenica.

The war began over a dispute between Corcyra and Epidamnus; the latter was a minor enough city that Thucydides has to tell his reader where it is. Corinth intervened on the Epidamnian side. Fearful lest Corinth capture the Corcyran navy (second only to the Athenian in size), Athens intervened. It prevented Corinth from landing on Corcyra at the Battle of Sybota, laid siege to Potidaea, and forbade all commerce with Corinth's closely situated ally, Megara (the Megarian decree).

There was disagreement among the Greeks as to which party violated the treaty between the Delian and Peloponnesian Leagues, as Athens was technically defending a new ally. The Corinthians begged Sparta for aid. Fearing the growing might of Athens, and witnessing Athens' willingness to use it against the Megarians (the embargo would have ruined them), Sparta declared the treaty to have been violated and the Peloponnesian War began in earnest.

The first stage of the war (known as the Archidamian War for the Spartan king, Archidamus II) lasted until 421 BC with the signing of the Peace of Nicias. The Athenian general Pericles recommended that his city fight a defensive war, avoiding battle against the superior land forces led by Sparta, and importing everything needful by maintaining its powerful navy: Athens would simply outlast Sparta, whose citizens feared to be out of their city for long lest the helots revolt. This strategy required that Athens endure regular sieges, and in 430 BC it was visited with an awful plague which killed appropximately a quarter of its people, including Pericles. With Pericles gone, less conservative elements gained power in the city and Athens went on the offensive. It captured 300–400 Spartan hoplites at the Battle of Pylos. This represented a significant fraction of the Spartan fighting force which the latter decided it could not afford to lose. Meanwhile, Athens had suffered humiliating defeats at Delium and Amphipolis. The Peace of Nicias concluded with Sparta recovering its hostages and Athens recovering the city of Amphipolis.

Those who signed the Peace of Nicias in 421 BC swore to uphold it for fifty years. The second stage of the Peloponnesian War began in 415 BC when Athens embarked on the Sicilian Expedition to support an ally (Segesta) attacked by Syracuse and conquer Sicily. Initially, Sparta was not going to aid its ally, but Alcibiades, the Athenian general who had argued for the Sicilian Expedition, defected to the Spartan cause upon being accused of grossly impious acts and convinced them that they could not allow Athens to subjugate Syracuse. The campaign ended in disaster for the Athenians.

Athens' Ionian possessions rebelled with the support of Sparta, as advised by Alcibiades. In 411 BC, an oligarchical revolt in Athens held out the chance for peace, but the Athenian navy, which remained committed to the democracy, refused to accept the change and continued fighting in Athens' name. The navy recalled Alcibiades (who had been forced to abandon the Spartan cause after reputedly seducing the wife of Agis II, a Spartan king) and made him its head. The oligarchy in Athens collapsed and Alcibiades proceeded to reconquer what had been lost.

In 407 BC, Alcibiades was replaced following a minor naval defeat at the Battle of Notium. The Spartan general Lysander, having fortified his city's naval power, won victory after victory. Following the Battle of Arginusae, which Athens won but was prevented by bad weather from rescuing some of its sailors, Athens executed or exiled eight of its top naval commanders. Lysander followed with a crushing blow at the Battle of Aegospotami in 405 BC which virtually destroyed the Athenian fleet. Athens surrendered one year later, ending the Peloponnesian War.

The war had left devastation in its wake. Discontent with the Spartan hegemony that followed (including the fact that it ceded Ionia and Cyprus to the Persian Empire at the conclusion of the Corinthian War (395–387 BC); see Treaty of Antalcidas) induced the Thebans to attack. Their general, Epaminondas, crushed Sparta at the Battle of Leuctra in 371 BC, inaugurating a period of Theban dominance in Greece. In 346 BC, unable to prevail in its ten year war with Phocis, Thebes called upon Philip II of Macedon for aid. Macedon quickly conquered the exhausted cites of Greece. The basic unit of politics from that point was the empire, and the Hellenic Age had begun.

Hellenistic Greece
The Hellenistic period of Greek history begins with the death of Alexander the Great in 323 BC and ends with the annexation of the Greek peninsula and islands by Rome in 146 BC. Although the establishment of Roman rule did not break the continuity of Hellenistic society and culture, which remained essentially unchanged until the advent of Christianity, it did mark the end of Greek political independence.

During the Hellenistic period the importance of "Greece proper" (that is, the territory of modern Greece) within the Greek-speaking world declined sharply. The great centres of Hellenistic culture were Alexandria and Antioch, capitals of Ptolemaic Egypt and Seleucid Syria respectively. (See Hellenistic civilization for the history of Greek culture outside of Greece in this period.)

Athens and her allies revolted against Macedon upon hearing that Alexander had died, but was defeated within a year in the Lamian War. Meanwhile, a struggle for power broke out among Alexander's generals, which resulted in the break-up of his empire and the establishment of a number of new kingdoms (see the Wars of the Diadochi). Ptolemy was left with Egypt, Seleucus with the Levant, Mesopotamia, and points east. Control of Greece, Thrace, and Anatolia was contested, but by 298 BC the Antigonid dynasty had supplanted the Antipatrid.

Macedonian control of the Greek city-states was intermittent, with a number of revolts. Athens, Rhodes, Pergamum and other Greek states retained substantial independence, and joined the Aetolian League as a means of defending it. The Achaean League, while nominally subject to the Ptolemies was in effect independent, and controlled most of southern Greece. Sparta also remained independent, but generally refused to join any league.

In 267 BC Ptolemy II persuaded the Greek cities to revolt against Macedon, in what became the Chremonidean War, after the Athenian leader Chremonides. The cities were defeated and Athens lost her independence and her democratic institutions. This marked the end of Athens as a political actor, although it remained the largest, wealthiest and most cultivated city in Greece. In 225 Macedon defeated the Egyptian fleet at Cos and brought the Aegean islands, except Rhodes, under its rule as well.

Sparta remained hostile to the Achaeans, and in 227 BC invaded Achaea and seized control of the League. The remaining Acheans preferred distant Macedon to nearby Sparta, and allied with the former. In 222 BC the Macedonian army defeated the Spartans and annexed their city—the first time Sparta had even been occupied by a foreign power.

Philip V of Macedon was the last Greek ruler with both the talent and the opportunity to unite Greece and preserve its independence against the ever-increasing power of Rome. Under his auspices the Peace of Naupactus (217 BC) brought conflict between Macedon and the Greek leagues to an end, and at this time he controlled all of Greece except Athens, Rhodes and Pergamum.

In 215 BC, however, Philip formed an alliance with Rome's enemy Carthage. Rome promptly lured the Achaean cities away from their nominal loyalty to Philip, and formed alliances with Rhodes and Pergamum, now the strongest power in Asia Minor. The First Macedonian War broke out in 212, and ended inconclusively in 205, but Macedon was now marked as an enemy of Rome.

In 202 BC Rome defeated Carthage, and was free to turn her attention eastwards. In 198 the Second Macedonian War broke out for obscure reasons, but basically because Rome saw Macedon as a potential ally of the Seleucids, the greatest power in the east. Philip's allies in Greece deserted him and in 197 he was decisively defeated at the Battle of Cynoscephalae by the Roman proconsul Titus Quinctius Flaminius.

Luckily for the Greeks, Flaminius was a moderate man and an admirer of Greek culture. Philip had to surrender his fleet and become a Roman ally, but was otherwise spared. At the Isthmian Games in 196, Flaminius declared all the Greek cities free, although Roman garrisons were placed at Corinth and Chalcis. But the freedom promised by Rome was an illusion. All the cities except Rhodes were enrolled in a new League which Rome ultimately controlled, and democracies were replaced by aristocratic regimes allied to Rome.

Roman Period
Militarily Greece itself declined to the point that the Romans conquered the land (168 BC onwards), though Greek culture would in turn conquer Roman life. Although the period of Roman rule in Greece is conventionally dated as starting from the sacking of Corinth by the Roman Lucius Mummius in 146 BC, Macedonia had already come under Roman control with the defeat of its king, Perseus, by the Roman Aemilius Paullus at Pydna in 168 BC. The Romans divided the region into four smaller republics, and in 146 BC Macedonia officially became a Roman province, with its capital at Thessalonica. The rest of the Greek city-states gradually and eventually paid homage to Rome ending their de jure autonomy as well. The Romans left local administration to the Greeks without making any attempt to abolish traditional political patterns. The agora in Athens continued to be the centre of civic and political life.

Caracalla's decree in 212 AD, the Constitutio Antoniniana, extended citizenship outside of Italy to all free adult males in the entire Roman Empire, effectively raising provincial populations to equal status with the city of Rome itself. The importance of this decree is historical rather than political. It set the basis for integration where the economic and judicial mechanisms of the state could be applied throughout the entire Mediterranean as was once done from Latium into all of Italy. In practice of course, integration did not take place uniformly. Societies already integrated with Rome, such as Greece, were favored by this decree, in comparison with those far away, too poor or just too alien such as Britain, Palestine or Egypt.

Caracalla's decree did not set in motion the processes that lead to the transfer of power from Italy and the West to Greece and the East, but rather accelerated them, setting the foundations for the rise of Greece as a major power in Europe and the Mediterranean in the Middle Ages.

Medieval Greece
The history of the Byzantine Empire is described by scholar August Heisenberg as the history "of the Roman state of the Greek nation, that turned Christian". The division of the empire into East and West and the subsequent collapse of the Western Roman Empire were developments that constantly accentuated the position of the Greeks in the empire and eventually allowed them to become identified with it altogether. The leading role of Constantinople began when Constantine the Great turned Byzantium into the new capital of the Roman Empire, henceforth to be known as Constantinople, placing the city at the centre of Hellenism a beacon for the Greeks that lasted to the modern era.

The figures of Constantine the Great and Justinian dominated during 324–610. Assimilating the Roman tradition, the emperors sought to provide the basis for subsequent developments and for the formation of the Byzantine Empire. Efforts to secure the borders of the Empire and to restore the Roman territories marked the early centuries. At the same time, the definitive formation and establishment of the Orthodox doctrine, but also a series of conflicts resulting from heresies that developed within the boundaries of the empire marked the early period of Byzantine history.

In the first period of the middle Byzantine era (610–867) the empire was attacked both by old enemies (Persians, Langobards, Avars and Slavs) as well as by new ones, appearing for the first time in history (Arabs, Bulgarians). The main characteristic of this period was that the enemy attacks were not localized to the border areas of the state but they were extended deep beyond, even threatening the capital itself. At the same time, these attacks lost their periodical and temporary character and became permanent settlements that transformed into new states, hostile to Byzantium. Changes were also observed in the internal structure of the empire which was dictated by both external and internal conditions. The predominance of the small free farmers, the expansion of the military estates and the development of the system of themes, brought to completion developments that had started in the previous period. Changes were noted also in the sector of administration: the administration and society had become immiscibly Greek, while the restoration of Orthodoxy after the iconoclast movement, allowed the successful resumption of missionary action among neighbouring peoples and their placement within the sphere of Byzantine cultural influence. During this period the state was geographically reduced and economically damaged, since it lost wealth-producing regions; however, it obtained greater lingual, dogmatic and cultural homogeneity.

The year 1204 marks the beginning of the late Byzantine period, when probably the most important event for the Empire occurred. Constantinople was lost for the Greek people for the first time, and the empire was conquered by Latin crusaders and would be replaced by a new Latin one, for 57 years. In addition, the period of Latin occupation decisively influenced the empire's internal development, as elements of feudality entered aspects of Byzantine life. In 1261 the Greek empire was divided between the former Greek Byzantine Comnenos dynasty members (Epirus) and Palaiologos dynasty (the last dynasty until the fall of Constantinople). After the gradual weakening of the structures of the Greek Byzantine state and the reduction of its land from Turkish invasions, came the fall of the Greek Byzantine Empire, at the hands of the Ottomans, in 1453, when the Byzantine period is considered to have ended.

It must be pointed out that the term "Byzantine" is a contemporary one established by historians. People used to call the Empire from the 10th century on as the Greek Empire as well as Romeo-Greek before that time; that's why Greeks call themselves sometimes as Romioi in a colloquial form. The Romeo term was used sometimes because of the legal tradition left in many aspects of the political administration of the Empire. It must be added also that many empires all around Europe had been using this term, in Addition to the Greek Byzantines, like the Carolingians, or the Heiliges Römisches Reich (Latin Sacrum Romanum Imperium) of the Germans looking themselves as the legitimate heirs of the Roman Empire.

Ottoman Rule and the Rise of Modern Greece

The Battle of Navarino, in October 1827, marked the effective end of Ottoman Rule in Greece.

When the Ottomans arrived, two Greek migrations occurred. The first migration entailed the Greek intelligentsia migrating to Western Europe and influencing the advent of the Renaissance. The second migration entailed Greeks leaving the plains of the Greek peninsula and resettling in the mountains. Greece being mostly mountainous, the Ottomans could not conquer the entire Greek peninsula since they created neither a military nor an administrative presence in the mountains. There existed many Greek mountain clans all across the peninsula and islands. The Sphakiots of Crete, the Souliots (or Souli) of Epirus, and the Mani (or Maniots) of Peloponnesus were the most resilient mountain clans throughout the Ottoman Empire. By the end of the 16th century up until the 17th century, many Greeks began to migrate from the mountains to the plains. The millet system contributed to the ethnic cohesion of Orthodox Greeks by segregating the various peoples within the Ottoman Empire based on religion.The Greek Orthodox Church, an ethno-religious institution, helped the Greeks from all geographical areas of the peninsula (i.e., mountains, plains, and islands) to preserve their ethnic, cultural, linguistic, and racial heritage during the harsh years of Ottoman rule. The Greeks living in the plains during Ottoman occupation were either Christians who dealt with the burdens of foreign rule or Crypto-Christians (Greek Muslims who were secret practitioners of the Greek Orthodox faith). Many Greeks became Crypto-Christians in order to avoid heavy taxes and at the same time express their identity by maintaining their secret ties to the Greek Orthodox Church. However, Greeks who converted to Islam and were not Crypto-Christians were deemed Turks in the eyes of Orthodox Greeks, even if they adopted no other form of Turkish culture or the Turkish language.

Creation of the Modern Greek State

The Ottomans ruled Greece until the early 19th century. In 1821, the Greeks rebelled in the Greek War of Independence and declared their independence, but did not succeed until 1829. The elites of powerful European nations saw the war of Greek independence, with its accounts of Turkish atrocities, in a romantic light (see, for example, the 1824 painting Massacre of Chios by Eugène Delacroix). Scores of non-Greeks volunteered to fight for the cause—including, for example Lord Byron—and indeed at times the Ottomans seemed on the point of almost entirely suppressing the Greek revolution but for the threatened direct military intervention of France, England or Russia. The Russian minister for foreign affairs, Ioannis Kapodistrias, himself a Greek, returned home as President of the new Republic following Greek independence. That republic disappeared when a few years later Western powers helped turn Greece into a monarchy, the first king coming from Bavaria and the second from Denmark. During the 19th and early 20th centuries, in a series of wars with the Ottomans, Greece sought to enlarge its boundaries to include the ethnic Greek population of the Ottoman Empire, slowly growing in territory and population until it reached its present configuration in 1947. In World War I, Greece sided with the entente powers against Turkey and the other Central Powers. In the war's aftermath, the Great Powers awarded parts of Asia Minor to Greece, including the city of Smyrna (known as Izmir today) which had a large Greek population. At that time, however, the Turkish nationalists led by Mustafa Kemal Ataturk, overthrew the Ottoman government, organised a military assault on the Greek troops, and defeated them. Immediately afterwards, hundreds of thousands of Turks then living in mainland Greek territory left for Turkey as an exchange with hundreds of thousands of Greeks living in Turkey.

Despite the country's numerically small and ill-equipped armed forces, Greece made a decisive contribution to the Allied efforts in World War II. At the start of the war Greece sided with the Allies and refused to give in to Italian demands. Italy invaded Greece on 28 October 1940, but Greek troops repelled the invaders after a bitter struggle (see Greco-Italian War). This marked the first Allied victory in the war. Hitler then reluctantly stepped in, primarily to secure his strategic southern flank: troops from Germany, Hungary, Bulgaria and Italy successfully invaded Greece, overcoming Greek, British, Australian and New Zealand units.

However, when the Germans attempted to seize Crete in a massive attack by paratroops—with the aim of reducing the threat of a counter-offensive by Allied forces in Egypt—Allied forces, along with Cretan civilians, offered fierce resistance. Although Crete eventually fell, this delayed German plans significantly, with the result that the German invasion of the Soviet Union started fatally close to winter. A recent alternative view of this event is that the German troops involved in the battle of Crete were not numerous enough to have any impact on the much larger assault against the Soviet Union.

During years of Nazi occupation, thousands of Greeks died in direct combat, in concentration camps or of starvation. The occupiers murdered the greater part of the Jewish community despite efforts by the Greek Orthodox Church and many Christian Greeks to shelter Jews. The economy languished. After liberation, Greece experienced an equally bitter civil war—between communists and royalists—that lasted until 1949.

In the 1950s and 1960s, Greece continued to develop slowly, initially with the help of the U.S. Marshall Plans' grants and loans, and later through growth in the tourism sector. In 1967, the Greek military seized power in a coup d'état, overthrew the right-wing government of Panayiotis Kanellopoulos and established what became known as the Régime of the Colonels. The Central Intelligence Agency was suspected in involvement in the coup. The new regime in Athens was supported by the U.S.. In 1973, the régime abolished the Greek monarchy. In 1974, dictator Papadopoulos denied help to the U.S. and rumor has it that as a result the U.S., through Kissinger's efforts, initiated a second coup. Colonel Ioannides was appointed as the new head-of-state.

Many hold Ioannides responsible for the coup against President Makarios of Cyprus—the coup seen as the pretext for the first wave of the Turkish invasion of Cyprus in 1974; see: the 1974 crisis between Greece and Turkey. The Cyprus events and the outcry following a bloody suppression of Athens Polytechnic uprising in Athens led to the implosion of the military régime. A charismatic exiled politician, Konstantinos Karamanlis, returned from Paris as interim prime minister and later gained re-election for two further terms at the head of the conservative Nea Dimokratia party. In 1975, following a referendum to confirm the deposition of King Constantine II, a democratic republican constitution came into force. Another previously exiled politician, Andreas Papandreou also returned and founded the socialist PASOK party, which won the elections in 1981 and dominated the country's political course for almost two decades.

Since the restoration of democracy, the stability and economic prosperity of Greece have grown. Greece joined the European Union in 1981 and adopted the Euro as its currency in 2001. New infrastructure, funds from the EU and growing revenues from tourism, shipping, services, light industry and the telecommunications industry have brought Greeks an unprecedented standard of living. Tensions continue to exist between Greece and Turkey over Cyprus and the delimitation of borders in the Aegean Sea but relations have considerably thawed following successive earthquakes—first in Turkey and then in Greece—and an outpouring of sympathy and generous assistance by ordinary Greeks and Turks.
