The Hōjō clan (北条氏 hōjō shi) in the history of Japan was a family who controlled the hereditary title of shikken (regent) of the Kamakura shogunate between 1203 and 1333. Despite the title, in practice the family wielded actual governmental power during this period compared to both the Kamakura shoguns, or the Imperial Court in Kyoto, whose authority was largely symbolic. The Hōjō are known for fostering Zen Buddhism and the development of Bushidō and for leading the successful opposition to the Mongol invasions of Japan. Resentment at Hōjō rule eventually culminated in the overthrow of the clan and the establishment of the Ashikaga shogunate.
