Kingdom of Champasak
The Kingdom of Champasak (Lao: ຈຳປາສັກ [tɕàmpàːsák]) or Bassac, (1713–1904) was a Lao kingdom under Nokasad, a grandson of King Sourigna Vongsa, the last king of Lan Xang and son-in-law of the Cambodian King Chey Chettha IV. Bassac and the neighboring principalities of Attapeu and Stung Treng emerged as power centers under what was later to be described as the Mandala Southeast Asian political model.
