Between 600 B.C. and 450 B.C., Athens changed the distribution of political power between the aristocracy and ordinary citizens. A. The rise of the city-state put enormous pressure on the aristocracy to change its traditional way of life to make it appear more in harmony with the values of classical Athenian culture. B. The aristocracy's monopoly on political power ended with Solon's reforms, and its political influence was further eroded by the centralization of administration under the tyrants. C. The aristocrats staged elaborate festivals that focused attention on Athens instead of the surrounding villages. D. Cleisthenes gave each tribe an equal number of council members, jurors, generals, and commissioners. E. Cleisthenes' reforms reduced aristocratic power by reorganizing the citizen body and changing the entry points to civic life so that political power did not rely on traditional family and clan structures. F. Over time, as the all-citizen assembly took on more and more of the actual exercise of political power, ordinary citizens participated in public life more fully than ever before.
