Hosokawa Tadaoki (細川忠興, November 28, 1563 – January 18, 1646) was a Japanese samurai warrior of the late Sengoku period and early Edo period.[1] He was the son of Hosokawa Fujitaka with Numata Jakō, and he was the husband of a famous Christian convert (Kirishitan), Hosokawa Gracia. For most of his life, he went under the name of Nagaoka Tadaoki that had been adopted by his father and was related to a town that was in their domain.[2] Shortly after the victory at Sekigahara, Nagaoka Tadaoki reverted to his original name Hosokawa Tadaoki.[3]
Biography
Tadaoki was the eldest son of Hosokawa Fujitaka.[4] He fought in his first battle at the age of 15. In that battle, he was in the service of Oda Nobunaga. His childhood name was Kumachiyo (熊千代).
Tadaoki was given the Province of Tango in 1580. Soon after that, he married Hosokawa Gracia, the daughter of Akechi Mitsuhide.
In 1582, Akechi Mitsuhide rebelled against Nobunaga and Nobunaga was killed. Akechi turned to Hosokawa Fujitaka and Hosokawa Tadaoki for help. They refused to help him, later Mitsuhide was defeated by Hideyoshi.
He was succeeded by Hosokawa Tadatoshi (1586–1641), who was present at the Siege of Shimabara (1637–1638). In 1632 Tadatoshi received a huge fief in Higo (Kumamoto, 540,000 koku), where the Hosokawa family remained until 1871.
In July 1600, Ishida Mitsunari had attempted to gain some leverage over those leaning towards Ieyasu by taking as hostages all those whose families were in Osaka Castle, this happened to include Tadaoki's wife, who was by now a Christian, baptized "Gracia". To avoid capture, Hosokawa Gracia ordered a servant to kill her and set fire to their quarters. While there is little reason to believe that Tadaoki was emotionally scarred by the incident, it was considered an appalling act of trickery, and served to drive Tadaoki into Ieyasu's side.
On October 20, 1600 at the Battle of Sekigahara, Tadaoki commanded 5,000 men in the Tokugawa vanguard and clashed with the forces of Shima Sakon. Afterwards, He was awarded a fief in Buzen (Kokura, 370,000 koku) and went on to serve at the Siege of Osaka (1614–1615).
