Matsudaira Hirotada (June 9, 1526 – April 3, 1549) was a daimyo and lord of Okazaki Castle in Mikawa Province during Japan’s turbulent Sengoku Period. He is best known as the father of Tokugawa Ieyasu, the founder of the Tokugawa shogunate.
Early Life and Rise to Power
Hirotada was the son of Matsudaira Kiyoyasu, the seventh head of the Mikawa Matsudaira clan. In his early years, he was known by several childhood names, including Senshomaru, Senchiyo, and Jirozaburo. After his father was assassinated in 1535, Hirotada came under the protection of Abe Sadayoshi, a loyal retainer of the Matsudaira clan.
With the support of the Imagawa clan, Hirotada was established as the lord of Okazaki Castle. This alliance with the Imagawa strengthened his position but also brought him into direct conflict with the powerful Oda clan.
Conflicts with the Oda Clan
In 1540, Oda Nobuhide attacked and captured Anjo Castle, which was under Matsudaira control. Nobuhide installed his son, Oda Nobuhiro, as the castle’s new lord. Despite assistance from Mizuno Tadamasa, Hirotada could not reclaim the castle, cementing a bitter rivalry with the Oda clan.
Marriage and Family
In 1541, Hirotada married Okichi, the daughter of Mizuno Tadamasa. In 1542, they had a son, Matsudaira Takechiyo, who would later become Tokugawa Ieyasu. However, tensions between Hirotada and his father-in-law, Mizuno Tadamasa, led to Hirotada divorcing Okichi in 1544. He subsequently married Makihime, the daughter of Toda Yasumitsu.
Military Struggles
Hirotada aligned with Imagawa Yoshimoto to combat Oda Nobuhide at the First Battle of Azukizaka in 1542. The coalition suffered a defeat, further weakening Hirotada’s position. In 1543, his uncle, Matsudaira Nobutaka, betrayed the family and allied with the Oda clan, exacerbating the clan's challenges.
Assassination and Legacy
In 1549, when Hirotada's son Takechiyo was only six years old, Hirotada was betrayed and assassinated by his own retainers, who had been bribed by the Oda clan. Despite his untimely death, Hirotada’s legacy endured through his son, who rose to unify Japan and establish the Tokugawa shogunate.
In 1612, decades after his death, Hirotada was posthumously awarded the court rank of Dainagon by Tokugawa Ieyasu, honoring his father’s role in the clan’s history.
