Greece's rich historical legacy is reflected by its 18 UNESCO World Heritage Sites, among the most in Europe and the world.Greece is a democratic and developed country with an advanced high-income economy, a high quality of life, and a very high standard of living.With the end of the Dark Ages, there emerged various kingdoms and city-states across the Greek peninsula, which spread to the shores of the Black Sea, Southern Italy ("Magna Graecia") and Asia Minor.These states and their colonies reached great levels of prosperity that resulted in an unprecedented cultural boom, that of classical Greece, expressed in architecture, drama, science, mathematics and philosophy.Welcome to the official website of the National Archaeological Museum of Athens, Greece.The National Archaeological Museum of Athens is the largest archaeological museum in Greece and one of the most important museums in the world devoted to ancient Greek art.
Attempts by some of the Greek city-states of Asia Minor to overthrow Persian rule failed, and Persia invaded the states of mainland Greece in 492 BC, but was forced to withdraw after a defeat at the Battle of Marathon in 490 BC.
Both Athens and Sparta were later overshadowed by Thebes and eventually Macedon, with the latter uniting the Greek world in the League of Corinth (also known as the Hellenic League or Greek League) under the guidance of Phillip II, who was elected leader of the first unified Greek state in history.
Following the assassination of Phillip II, his son Alexander III ("The Great") assumed the leadership of the League of Corinth and launched an invasion of the Persian Empire with the combined forces of all Greek states in 334 BC.
Undefeated in battle, Alexander had conquered the Persian Empire in its entirety by 330 BC.
By the time of his death in 323 BC, he had created one of the largest empires in history, stretching from Greece to India.
