Minamoto no Yoritomo

was the founder and the first shogun of the Kamakura shogunate of Japan, ruling from 1192 until 1199, also the first shogun in the history of Japan. He was the husband of Hōjō Masako who acted as regent (shikken) after his death. Yoritomo was the son of Minamoto no Yoshitomo and belonged to Seiwa Genji's prestigious Kawachi Genji family. After setting himself the rightful heir of the Minamoto clan, he led his clan against the Taira clan from his capital in Kamakura, beginning the Genpei War in 1180. After five years of war, he finally defeated the Taira clan in the Battle of Dan-no-ura in 1185. Yoritomo thus established the supremacy of the warrior samurai caste and the first shogunate (bakufu) at Kamakura, beginning the feudal age in Japan, which lasted until the mid-19th century. Early life Yoritomo was the third son of Minamoto no Yoshitomo, heir of the Minamoto (Seiwa Genji) clan, and his official wife, Yura-Gozen, daughter of Fujiwara no Suenori, High Priest of Atsuta Shrine and a member of the powerful Fujiwara clan. Yoritomo was born in the family villa, on the western side of Atsuta Shrine, in Atsuta, Nagoya, Owari Province (present-day Seigan-ji). At the time, his grandfather Minamoto no Tameyoshi was the head of the Minamoto clan. His childhood name was Oniwakamaru (鬼武丸). He was a descendant of Emperor Seiwa.
