Hasari
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
The Hasari were a race of people (or possibly a political organization) that ruled over a "nation". This "nation" was seized by the Cylons, an event which prompted the Colonies to liberate the Hasari "nation" and marked the beginning of the Thousand-Yahren War. It is unclear what relationship the Colonies and Hasari shared, or even if the Hasari were still in existence during the timeframe of TOS.
