Matsudaira Chikatada served as a bushō from the mid-Muromachi to Sengoku periods. Chikatada served as the fourth head of the Matsudaira clan of Mikawa Province. He was the six-generation-prior grandfather of Tokugawa Ieyasu.
Initially, Chikatada was based in the Kamoda township in the Nukata District of Mikawa, but, around 1488 or 1489, his father, Matsudaira Nobumitsu, died so he inherited the headship of the clan and became the first head of the Anjō-Matsudaira family and the lord of Anjō Castle. After a while, he entered the priesthood and adopted the monk’s name of Seichū. The legacy of his governance is relatively unknown, and, as the third son of Nobumitsu, questions remain whether he in fact succeeded his father. Chikatada’s eldest brother, Matsudaira Moriie, was separated from the main branch to establish the Takenoya-Matsudaira family, an illegitimate branch of the clan, based in Takenoya in the Hoi District of Mikawa Province.
According to chronicles of Mikawa, Nobumitsu transferred headship of the clan to his eldest son while Chikatada was only the head of a cadet family. Later, however, prominent figures from the Matsudaira clan including Matsudaira Kiyoyasu and Tokugawa Ieyasu originated from the Anjō-Matsudaira so Chikatada was treated as the fourth head of the main branch of the Matsudaira.
In 1467, at the First Battle of Idano in the township of Ida, Chikatada defeated forces from Shinano and Iho. In 1470, he built the Iga-Hachiman Shrine that remains in the town of Ida in the city of Okazaki. In 1475, to mourn for those who were killed in action at the Battle of Idano, Chikatada founded the Daiji Temple to serve as the family temple for the Matsudaira clan on the ruins of the township of Kamoda. In 1477, he served as the founder for the restoration of the Daion Temple.
In 1487, he decimated Amano Kagetaka of Asō Castle and had his ninth son, Matsudaira Norikiyo, separate and found the Takiwaki-Matsudaira family. In 1493, at the Second Battle of Idano, Chikatada gained renown by defeating the Abe clan of Ueno Castle, the Suzuki clan of Terabe Castle, the Chūjō of Koromo Castle, the Miyake of Iho Castle, and the Nasu of Yakusa Castle.
In 1496, Chikatada transferred headship of the clan to his third son, Matsudaira Nagachika, and retired. He also had sons separate and found the Ogyū-Matsudaira and Takiwaki-Matsudaira families. His fourth son, Matsudaira Zongyū entered the priesthood, serving as the abbot of the Shinkōmyō Temple followed by the Chion Temple in Kyōto – the principal temple of the Jōdo, or Pure Land, sect of Buddhism, deepening relations with the Imperial Court.
On 8/10 of Bunki 1 (1501), Chikatada died at the age of seventy-one (or, under another theory, at the age of sixty-three).
