[1][2][3] In 1600, after the Battle of Sekigahara, Mimasaka Province was ruled by Kobayakawa Hideaki, the daimyō of Okayama Domain.

In 1697, his 5th generation successor Mori Sugutoshi went insane in Ise Province on his way to Edo to fulfill his sankin kōtai duties.

The "madness" may have been an excuse, as Sugutoshi had been in charge of constructing dog kennels outside Edo as part of Shogun Tokugawa Tsunayoshi's highly unpopular and ridiculed law against cruelty to animal and Sugutoshi reportedly fell into a rage on hearing that a ronin had broken into the kennel, slaughtering many dogs, which had resulted in the shogunate ordering the execution of a number of his retainers for negligence.

The domain was reduced to 100,000 koku, and transferred to a branch of the Echizen-Matsudaira clan whose ancestor was Yūki Hideyasu.

In 1765, the 5th daimyō, Matsudaira Yasuchika, opened a han school, the Kakuzankan (鶴山館), which lasted into the early Meiji period.
