Pisistratus was succeeded by his two sons, but the Athenians did not take kindly to their rule. Before long the tyranny came to an end. The Athenians now found a leader in a noble named Clisthenes, who proved to be an able statesman. He carried still further the democratic movement begun by Draco and Solon. One of his reforms extended Athenian citizenship to many foreigners and emancipated slaves ("freedmen") then living in Attica. This liberal measure swelled the number of citizens and helped to make the Athenians a more progressive people. Clisthenes, it is said, also established the curious arrangement known as ostracism. Every year, if necessary, the citizens were to meet in assembly and to vote against any persons whom they thought dangerous to the state. If as many as six thousand votes were cast, the man who received the highest number of votes had to go into honorable exile for ten years. [25] Though ostracism was intended as a precaution against tyrants, before long it came to be used to remove unpopular politicians. ATHENS A DEMOCRATIC STATE There were still some steps to be taken before the rule of the people was completely secured at Athens. But, in the main, the Athenians by 500 B.C. had established a truly democratic government, the first in the history of the world. The hour was now rapidly approaching when this young and vigorous democracy was to show forth its worth before the eyes of all Greece. 29. COLONIAL EXPANSION OF GREECE (ABOUT 750-500 B.C.) THE GREAT AGE OF COLONIZATION While Athens, Sparta, and their sister states were working out the problems of government, another significant movement was going on in the Greek world. The Greeks, about the middle of the eighth century B.C., began to plant numerous colonies along the shores of the Mediterranean and of the Black Sea. The great age of colonization covered more than two hundred years. [26] REASONS FOR FOUNDING COLONIES Several reasons led to the founding of colonies. Trade was an important motive. The Greeks, like the Phoenicians, [27] could realize large profits by exchanging their manufactured goods for the food and raw materials of other countries. Land hunger was another motive. The poor soil of Greece could not support many inhabitants and, when population increased, emigration afforded the only means of relieving the pressure of numbers. A third motive was political and social unrest. Greek cities at this period contained many men of adventurous disposition who were ready to seek in foreign countries a refuge from the oppression of nobles or tyrants. They hoped to find in their new settlements more freedom than they had at home. CHARACTER OF THE GREEK COLONY
