Greece was the birthplace of European civilisation. The period from 700BC saw the rise of the great city states of Athens, Corinth and Sparta, frequently engaged in long struggles for supremacy, and uniting only when faced with the common threat of invasion by the Persian Empire. The zenith was reached in the fifth century BC when Athens became the cultural and artistic centre of the Mediterranean, producing magnificent works of architecture, sculpture, drama and literature. Athens lost her empire through a mutually destructive struggle with her arch rival Sparta. The nation was then forcibly united under Alexander the Great. After defeating the sagging military might of Persia in a number of major battles, the expansion of the empire spread Greek influence through the East as far as India and through Egypt. The empire fragmented after Alexanders death in 323 BC, and the fall of Greek hegemony was completed when the country came under the sway of Rome. Under the Roman emperor Constantine, the empire gained a new capital in Constantinople, and Greece came under the control of the Eastern Empire when the empire divided. The Byzantines were, however, unable effectively to defend the whole of their empire from invaders, and only occasionally did Greece enjoy the security of effective imperial rule. The major beneficiaries of this were the Venetians, who increased their influence in Greece and other parts of the empire |
