Hōjō clanThe Hōjō clan was a Japanese samurai 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 political power in Japan 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 for leading the successful opposition to the Mongol invasions of Japan.
