Y?ki Hideyasu ( 結城 秀康 , 1 March 1574 – 2 June 1607) was a Japanese samurai who lived during the Azuchi?Momoyama and early Edo periods . He was the daimy? of Fukui Domain in Echizen . ^[1]

Early life [ edit ]

Hideyasu was born as Tokugawa Ogimaru ( ?川於義丸 ) in 1574, the second son of Tokugawa Ieyasu , by Lady Oman (also known as Lady Kog?), a handmaiden to his wife, Lady Tsukiyama . When Oman became pregnant, Ieyasu feared his wife's wrath, so he sheltered the girl in the home of his retainer Honda Shigetsugu , in Ofumi Village near Hamamatsu Castle , and it was there that Ogimaru and his brother were born. ^{[ citation needed ]}

Oman is said to have given birth to twins, and that Ogimaru's brother succeeded Oman's father as priest of Chiry? Shrine in Mikawa Province . ^{[ citation needed ]}

The young Ogimaru was, for some reason, disliked by his father Ieyasu. It was not until age three that he met Ieyasu, and even that meeting, cold as it was, was not arranged by the father, but instead by Ogimaru's elder half-brother, Matsudaira Nobuyasu . After Oda Nobunaga demanded that Ieyasu order Nobuyasu's seppuku , Ogimaru would have been the next in line to inherit the Tokugawa headship by birth; however, as part of the peace negotiations following the Battle of Komaki-Nagakute , he was given in adoption (in reality as a hostage) to the childless Hashiba Hideyoshi in 1584. ^[2] Coming of age while living with Hideyoshi, Ogimaru was given the name Hashiba Hideyasu , which combined the names of his adoptive father and biological father. He was also granted courtesy title of Mikawa-no-kami , and his Court rank was Senior Fifth Rank, Lower Grade, raised to Ukonoue-gon-sh?sh? and Senior Fourth Rank, Lower Grade in 1585

Mature years [ edit ]

Hideyasu took part in his first campaign during the Ky?sh? Campaign of 1587, leading the assault on Buzen-Iwaishi Castle. He also received honors for his distinction in the pacification of Hy?ga Province . Hideyasu also took part in the Siege of Odawara (1590) and the Japanese invasions of Korea (1592?98) . His successes in these campaigns earned him respect as an able field commander, despite his youth. ^{[ citation needed ]}

However, in 1589, a natural son was born to Toyotomi Hideyoshi. Hideyoshi had adopted several promising candidates as heir over the years, and began to give these men in adoption to other great houses to avoid a potential conflict over the succession. Hideyasu was given in adoption in 1590 to Y?ki Harutomo of Shim?sa Province , and married Harutomo's niece, becoming Y?ki Hideyasu and succeeded to the Y?ki headship and its 101,000 koku holding. ^[2]

Later years [ edit ]

During the Battle of Sekigahara , Y?ki Hideyasu was ordered by Ieyasu to remain in his holdings in Shim?sa, possibly because of his pro-Toyotomi sympathies, and possibility because his emergence as a strong military leader might threaten the prestige and position of his younger half-brother, Tokugawa Hidetada . Following the Battle of Sekigahara and the establishment of the Tokugawa shogunate , he was given all of Echizen Province (670,000 koku ) as his fief. In 1604, he was allowed to take the surname Matsudaira . ^[3] In 1605, his court rank was elevated to Senior Third Rank, and his courtesy title to Gon-Ch?nagon . Professor Sunao Kawaguchi suspected the reason Hideyasu was not appointed as successor of Ieyasu as Shogun was because he spent most of his life close to the house of Toyotomi clan . ^[4]

Hideyasu died in 1607 at the age of 34, possibly from syphilis . His death came seven years after the Battle of Sekigahara and eight years before Tokugawa Ieyasu completed the destruction of the Toyotomi clan at the Siege of Osaka . He left a will to his heir urging support for Toyotomi Hideyori even if the Tokugawa decided to attack. His son and heir, Matsudaira Tadanao ignored his father's will and thus the Echizen-Matsudaira clan survived to the Meiji restoration of 1868. ^[2]
