Athenian democracy developed around the 6th century BC in the Greek city-state of Athens, comprising the city of Athens and the surrounding territory of Attica. Although Athens is the most famous ancient Greek democratic city-state, it was not the only one, nor was it the first; multiple other city-states adopted similar democratic constitutions before Athens. By the late 4th century BC, as many as half of the over one thousand existing Greek cities might have been democracies. Athens practiced a political system of legislation and executive bills. Participation was open to adult, free male citizens Adult male citizens probably constituted no more than 30 percent of the total adult population. Solon, Cleisthenes, and Ephialtes contributed to the development of Athenian democracy. Cleisthenes broke up the unlimited power of the nobility by organizing citizens into ten groups based on where they lived, rather than on their wealth. The longest-lasting democratic leader was Pericles. After his death, Athenian democracy was twice briefly interrupted by oligarchic revolutions in 411 and 404 BC, towards the end of the Peloponnesian War. It was modified somewhat after it was restored under Eucleides; the most detailed accounts of the system are of this fourth-century modification, rather than the Periclean system. Democracy was suppressed by the Macedonians in 322 BC. The Athenian institutions were later revived, but how close they were to a real democracy is debatable.
