Ietada was the fourth son of Matsudaira Koretada, who was the head of the Fukōzu branch of the Matsudaira clan. Ietada served his brother Tokugawa Ieyasu from a young age.[1]

In 1572, he fought at the Battle of Mikatagahara.[2] He fought in many of Ieyasu's campaigns, including against Takeda Katsuyori in the Battle of Nagashino 1575.[1] and took part in the Siege of Takatenjin (1581) against Okabe Motonobu.

In 1590, Ietada was granted Oshi Domain (100,000 koku) in Musashi Province. He was transferred to Kashira Domain in 1592 and to Omigawa Domain in 1594.[1]

In 1599, he was given command of Fushimi Castle near Kyoto.[1] He was killed fighting against Ishida Mitsunari at the siege of Fushimi in 1600.[3]


Ietada is known for his journal, Ietada nikki (家忠日記), which he kept for the 17 year interval between 1575 and August 1594.[4]
