trittys

In ancient Greece, particularly in Athens, the trittys was a division of a tribe. Following the reforms of Cleisthenes around 508 BCE, the citizen body was reorganized into 10 new tribes. Each of these tribes was composed of three trittyes, which were geographical subdivisions. These trittyes were categorized as "inland," "coastal," and "city," and each of the 139 demes (townships) belonged to a specific trittys and tribe. This reorganization aimed to integrate citizens from across Attica into the political and military structure of Athens, moving away from a system based purely on descent. The trittys system was a fundamental component of Cleisthenes' reforms, which laid the groundwork for Athenian democracy.12
