The first family being extinct in 1205, Ashikaga Yoshizumi, son of
Ashikaga Yoshikane, was chosen by
Hōjō Tokimasa to revive the name of Hatakeyama. He married Tokimasa's daughter, the widow of
Hatakeyama Shigeyasu (the last Hatakeyama of the first branch), and inherited the domains of the Hatakeyama (1205). Thus the new family descended from the Minamoto (Seiwa Genji). The clan was an ally of the
Ashikaga shogunate against the (Imperial) Southern Court during the wars of the
Nanboku-chō period, and was rewarded by the shogunate with the hereditary position of
shugo (Governor) of the provinces of
Yamashiro,
Kii,
Kawachi,
Etchū, and
Noto, at the end of the 14th century. During the 15th century, the members of the Hatakeyama clan held, although not exclusively, the title of
kanrei (Shōgun's Deputy), holding great influence over the Imperial Court at
Kyoto. Around 1450, there was a split in the clan, and the internal conflict weakened the clan as a whole, causing it to lose the position of
kanrei to the
Hosokawa clan. This split began with a feud between
Hatakeyama Masanaga and
Hatakeyama Yoshinari over succession to the position; it quickly grew, as each side gained allies, and was one of the sparks that ignited the
Ōnin War. Nevertheless, the Hatakeyama maintained enough strength and unity to become some of
Oda Nobunaga's chief adversaries in Kyoto, a hundred years later. ==Sengoku period==
