北条政子
By 1185, the Taira were completely defeated at the Battle of Dan-no-ura. Munemori was executed, while the remaining Taira either were executed or drowned, including the young Emperor Antoku. Minamoto no Yoritomo was now the undisputed leader of Japan. Hōjō Masako and her family had stood by Yoritomo through it all. She rode with him on his campaigns and was never defeated in battle.
