佐賀藩
Ogi Domain was originally a sub-domain of the Saga Domain, founded in 1642 for Nabeshima Motoshige, the eldest son of the first "daimyō" of Saga Domain, Nabeshima Katsushige. Although Motoshige was the eldest son, he was displaced in the line of succession for Saga Domain by his younger half-brother, Nabeshima Tadanao, whose mother was a daughter of "shōgun" Tokugawa Ieyasu.
