Hirotada was the son of [[Matsudaira Kiyoyasu]]. His father had been slain when he was about ten and for a time he was protected by [[Abe Sadayoshi]]. With the aid of the [[Imagawa clan]], Abe was able to have Hirotada safely installed at [[Okazaki castle]]. He allowed the Matsudaira to come under the influence of the Imagawa and fought with the [[Oda clan (Owari)|Oda]] of Owari, who took [[Anjo castle]] in [[1540]]. In [[1541]] Hirotada married the daughter of [[Mizuno Tadamasa]] (she is known as [[Dai no kata]]) and she gave birth to the future Tokugawa Ieyasu the next year. Hirotada divorced Dai no kata after the [[Mizuno clan|Mizuno]] betrayed him in [[1544]] and married the daughter of [[Toda Yasumitsu]], a union that produced a son (Iemoto) and three daughters. He was defeated by the Oda along with the Imagawa at the [[First Battle of Azukizaka]] the following year and suffered the defection of his uncle, [[Matsudaira Nobutaka]], to the Oda. Hard-pressed by [[Oda Nobuhide]], Hirotada asked the Imagawa for more assistance and was compelled to send his son as a hostage to the Imagawa's capital of Sumpu in [[Suruga province]]. The child (the future Tokugawa Ieyasu) was intercepted en route by the Oda and kept at [[Nagoya]] for a number of years. Hirotada was defeated in an attempt to retake Anjo and survived an assassination attempt by [[Iwamatsu Hachiya]]. The Imagawa and Matsudaira defeated the Oda at the [[second Battle of Azukizaka]] in [[1548]] but Hirotada died of illness the following year. In [[1612]] his son Ieyasu, now a retired [[Shogun|shôgun]], requested that rank of Dainogon be posthumously conferred on Hirotada. | Hirotada was the son of [[Matsudaira Kiyoyasu]].
