The culture of Greece has evolved over thousands of years, beginning in Mycenaean Greece, continuing most notably into Classical Greece, through the influence of the Roman Empire and its successor the Byzantine Empire. Other cultures and states such as the Persian Empire, Latin and Frankish states, theOttoman Empire, the Venetian Republic, Genoese Republic, and British Empire have also left their influence on modern Greek culture, but historians credit theGreek War of Independence with revitalising Greece and giving birth to a single entity of its multi-faceted culture.In ancient times, Greece was the birthplace of Western culture and democracy. Modern democracies owe a debt to Greek beliefs in government by the people, trial by jury, and equality under the law. The ancient Greeks pioneered in many fields that rely on systematic thought, including biology, geometry, history,philosophy, and physics. They introduced such important literary forms as epic and lyric poetry, history, tragedy, and comedy. In their pursuit of order and proportion, the Greeks created an ideal of beauty that strongly influenced Western art.
