Takasaki Domain

During the Battle of Odawara in 1590, Toyotomi Hideyoshi dispatched an army led by Uesugi Kagekatsu and Maeda Toshiie and destroyed Wada Castle.

After Tokugawa Ieyasu took control over the Kantō region in 1590, he assigned Ii Naomasa, one of his most trusted Four Generals to nearby Minowa Castle, with revenues of 120,000 koku.

Ii Naomasu relocated to the site in 1598, renaming it Takasaki, and bringing with him the population of Minowa to form the nucleus of a new castle town.

Ii Naomasa was transferred to Hikone Domain, and Takasaki given to Sakai Ietsugu in 1604 with its revenues reduced to 50,000 koku.

During the Bakumatsu period, forces of Takasaki Domain played a role in the suppression of the Tengutō Rebellion and the final daimyō, Matsudaira Teruna was ordered by the shogunate to defend Kōfu Castle during the Boshin War.
