Overview
The was a powerful noble clan of Baekje, one of the Three Kingdoms of Korea.
Origins
The Hae clan was probably the royal house before the Buyeo clan replaced them, and both clans appear descended from the lineage of Buyeo and Goguryeo. The royal family of Buyeo had the surname "Hae". The founding monarch of Goguryeo, Jumong had the surname "Hae" but the surname was changed to Go (高). The character (解) means "to loosen; to unfasten; to untie or to explain". It also means "sun" in Korean as Buyeo, Goguryeo and Baekje were deeply involved in Sun Worship.
Baekje
They were one of the "Great Eight Families" (Daeseongpaljok, 大姓八族) of Baekje: (Sa (沙氏), Yeon (燕氏), Hyeop (劦氏), Hae (解氏), Jin (眞氏), Guk (國氏), Mok (木氏), and Baek (苩氏)). For generations the Hae monopolized providing queens for the Royal Family along with their rival, the Jin clan. This helped them gain high court positions in the government and military.
After the Battle at Mt. Amak fortress (阿莫山城) against Silla during the beginning of the reign of King Mu of Baekje the Great Eight Families lost a great deal of power. Among the families the Hae clan (who had led the battle), Hyeop, Jin and Mok disappeared from the central political stage leaving only the Yeon, Guk and Baek clans. The Sa clan promoted their influence by military force and produced a queen in the late reign of Mu of Baekje.
