The first traces of human life in Greece appeared in the Palaeolithic period (12,000-10,000 BC). Shortly afterwards during the Neolithic period (7,000-3,000 BC) we can find the first signs of the development of Greek civilization. The Copper Age (3.000-1.100 BC) in Minoan Crete the first writing systems and the first organized palatial/royal societies appeared in the beginning of the 2nd millennium. The Mycenaeans, taking advantage of the collapse of the Cretan civilization, established themselves as the dominant leadership/power until the last centuries of the 2nd millennium. After these years, the Mycenaeans had a dark period of economic and cultural stagnation (1.150-900 BC ), that ended with the appearance and commencement/beginning of the Geometric period (9th-8th century BC). The Archaic period (7th-6th century BC) was a time of great changes in social and political terms. The Classical period (5th-4th century) finds Athens the dominant political and cultural power of the country.During this period the Golden Age of Pericles appears (Parthenon, Platon, Aristotle, Sophocles, Euripides, Aristophanes). In the 4th century after the decline of Athens, Macedonia became a new dominant power in the Hellenic world. Afterwards, the time of Alexander the Great follows.The Romans conquered Greece in 146 BC. and in the 4th century Constantine moved the capital of the empire to Constantinople, a precursor of the Byzantine period in the country. The occupation of Greece from the Ottoman Empire follows, which begins with the fall of Constantinople in 1453, and ends with the Greek Revolution/Greek war of independence (1821). The final form of Greece through various liberation struggles and various incorporations was completed/finalized in 1948. In 1952 Greece became a member of NATO. Thereafter It follows a dark period of dictatorship in Greece 1967-1974. Greece became a member of the European Union in 1981.
