The Khitans ruled from their capital at Balasagun (in today's Kyrgyzstan), directly controlling the central region of the empire. The rest of their empire consisted of highly autonomous vassalized states, primarily Khwarezm, the Karluks, the Kingdom of Qocho of the Uyghurs, the Kankalis, and the Western, Eastern, and Fergana Kara-Khanids. The late-arriving Naimans also became vassals, before usurping the empire under Kuchlug.
