The 1333 siege of Kamakura was a battle of the Genkō War, and marked the end of the power of the Hōjō clan, which had dominated the regency of the Kamakura shogunate for over a century. Forces loyal to Emperor Go-Daigo and led by Nitta Yoshisada entered the city from multiple directions and destroyed it; in the end, the Hōjō leaders retreated to Tōshō-ji, the Hōjō family temple, where they committed suicide with the rest of the clan.
