Matsudaira Hirotada

was the lord of Okazaki Castle in Mikawa province, Japan during the Sengoku Period of the 16th century. He is best known for being the father of Tokugawa Ieyasu, founder of the Tokugawa Shogunate. Biography Hirotada was the son of Matsudaira Kiyoyasu (seventh head of the Mikawa Matsudaira clan). He was known in his childhood as Senshōmaru, Senchiyo, and Jirōzaburō. After his father's assassination in 1535, Hirotada was placed under the protection of a loyal retainer, Abe Sadayoshi. He allied with the Imagawa, and with their help was installed at Okazaki castle. The alliance with them brought him into conflict with the Oda clan. In 1540, Oda Nobuhide attacked and took Anjō castle, which was held by the Matsudaira family. Hirotada was assisted by Mizuno Tadamasa. After Anjō castle was taken, Oda Nobuhide's son, Oda Nobuhiro, was installed as the lord of the castle.
