細川 高国
His father was Hosokawa Masaharu, who was the branch of the Hosokawa clan.
Takakuni supported Hosokawa Sumimoto and got cr for putting down Sumiyuki. Because of that, he participated in the Muromachi shogunate in depth. In 1508, when Ōuchi Yoshioki marched his armies into Kyoto with Ashikaga Yoshiki (Ashikaga Yoshitane), the former shogun who had escaped to Suo Province, Takakuni conspired with them and purged the shogun Ashikaga Yoshizumi and Sumimoto to Ōmi Province.
Takakuni and Yoshioki took hold of the Muromachi shogunate.
Takakuni took over as head of the Hosokawa people and took the blam of Kanrei. In addition, he also held the post of Shugo of Settsu Province, Tamba Province, Sanuki Province and Tosa Province.
In 1518, he monopolized the powers of the shogunate after Yoshioki went back to his domain. In 1521, Yoshiki hated to be a puppet shogun, and escaped to Awa Province.
Takakuni made Ashikaga Yoshiharu, son of Yoshizumi, take up the post of shogun.
Takakuni took Yanagimoto Kataharu, the younger brother of Kozai Motomori, chief vassal of the Hosokawa people, as his wakashu and the two swore eternal love to each other. Kataharu, even after reaching adulthood, remained a favorite vassal. Though initially appeased by his lord, Yanagimoto shortly after joined with another brother against the cousin to avenge Motomori"s death.
In 1527, he was purged from Kyoto by Miyoshi Motonaga and Hosokawa Harumoto.
In 1531, his army was defeated, and he hid in a store room for alcoholic beverage at Amagasaki, Settsu Province. When he was detected, he committed suicide.
