Ieyasu-Nobunaga Alliance (1562–1582)
In 1563, Matsudaira Nobuyasu, the first son of Motoyasu, was married to Oda Nobunaga's daughter Tokuhime. In February, Matsudaira Motoyasu changed his name to Matsudaira Ieyasu. Some historians believe that these actions provoked the pro-Imagawa faction, including the Sakurai and Okusa Matsudaira families, which led to the simultaneous uprising against Ieyasu in the following year.
