Ōtomo clan
The Ōtomo clan (大友氏, Ōtomo-shi) was a Japanese samurai family whose power stretched from the Kamakura period through the Sengoku period, spanning over 400 years. The clan's hereditary lands lay in Kyūshū.
The first family head, Ōtomo Yoshinao (1172–1223), took the name from the Ōtomo territory in Sagami Province. The clan claims descent from Emperor Seiwa (850-881) through the Seiwa Genji lineage of the Minamoto clan. Although the clan genealogy claims Yoshinao to be an illegitimate son of Minamoto no Yoritomo, it has been concluded that he was in fact a descendant of the Fujiwara clan.
Following the establishment of the Kamakura shogunate in 1185, Yoshinao was granted the post of Governor (Shugo) of Bungo and Buzen Provinces in Kyūshū.
Ōtomo Yoshinao's descendants served as Governor of Buzen and Bungo Provinces for generations further establishing the power of Ōtomo clan in these two provinces. The clan would expand their power in Bungo Province along with the Shiga clan, founded by Yoshinao's eighth son Shiga Yoshisato, that had settled there earlier.
As the Ōtomo were one of the major clans of Kyūshū, along with the Shōni and the Shimazu, they had a central role in organizing efforts against the Mongol invasions of Japan in 1274 and 1281.
They also played an important role in the establishment of the Ashikaga shogunate, in the 1330s. Ōtomo warriors fought alongside those of Ashikaga Takauji and enabled him to win a number of key battles, including the battle of Sanoyama; this helped to ensure them powerful government positions in the new shogunate. Following the unrest of the Nanboku-chō period, the clan became an influential Shugo Daimyo family in Bungo, Buzen, and Chikugo Provinces during the Muromachi period.
Yoshinaga, 19th generation descendant of Yoshinao, along with his son Yoshiaki further became Sengoku period Daimyos. At the time of 21st generation Yoshishige, the Ōtomo clan reached its zenith by expanding its power to Hizen, Higo, and Chikuzen Provinces. At its zenith, the Ōtomo clan ruled six provinces (Buzen, Bungo, Hizen, Higo, Chikuzen and Chikugo) and two half-provinces (Hyūga and Iyo).
Towards the end of the 16th century, the Ōtomo fought both the Shimazu and Mōri clans, the latter of whom were expert sailors. Though they did not play a major role in the campaigns of Tokugawa Ieyasu which ended the Sengoku period, they did retain their domains into the Edo period.
