They were the most powerful of the noble families and had been comrades in arms with the founding monarch Onjo of Baekje.
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.
They did not lose their status as central nobles during the reign of the last King, Uija of Baekje by colluding with royal authority.
In the late Baekje all the Great Eight Families except for Sa and Guk clans lost their status as the central nobles and were degraded to local influence at last.
