What was the purpose of Solon’s Council of Four Hundred?

The primary purpose of the Council of Four Hundred, established by the Athenian statesman Solon as part of his constitutional reforms, was to prepare business for the Ecclesia, or general assembly.12

By creating this body, Solon introduced a deliberative council—or boule—to guide the work of the assembly. This reform served to balance the influence of the existing Areopagus, which remained a powerful conservative force in Athenian politics. While the Areopagus retained its role as a "guardian of the laws," the new Council of Four Hundred ensured that the assembly had a structured agenda for its deliberations, thereby laying foundational elements for the future development of Athenian democracy. Membership in this council was open to citizens from the top three income classes, further shifting political participation away from a strict monopoly by the aristocracy.123
