What form of government was first introduced in Athens Greece in 508BC?

Answer 1

Although historical records are not completely clear, it is generally agreed that near the beginning of the 5th century B.C.E., democracy first appeared in Athens -- and perhaps this was its first appearance throughout the world. Under the leadership of Cleisthenes, the Athenians overcame yet another dictatorial ruler and then instituted a variety of reforms that placed power in the hands of citizens and otherwise instituted democratic practices throughout Athenian government.
