The Federated Suns is an interstellar nation set within the fictional BattleTech game universe introduced by FASA Corporation in the 1980s. The Federated Suns have been ruled by the Davion Family, or House Davion, since the nation's founding in 2317. Much of House Davion's growth over the past 200 years has taken place at the expense of Liao's Capellan Confederation. This was particularly true at the end of the Fourth Succession War, when the Federated Suns took more than 100 worlds from House Liao.
