In 1600, after the
Battle of Sekigahara,
Ikeda Tsuneoki's third son,
Ikeda Nagayoshi (
Ikeda Terumasa's younger brother) was awarded estates in Hōki Province with a
kokudaka of 60,000
koku by
Tokugawa Ieyasu. This marked the start of Tottori Domain. In 1615, his son Ikeda Nagayoshi (長幸) was transferred to
Bitchū-Matsuyama Domain, and in his place,
Ikeda Mitsumasa (the eldest son of
Ikeda Toshitaka, the son of Ikeda Terumasa) was transferred from
Himeji Domain to an expanded Tottori Domain (325,000
koku) which now included most of
Inaba Province as well as Hōki Province. During his 16 year tenure, he built the foundations of the
castle town of Tottori. In 1632, when his uncle Ikeda Tadao, of
Okayama Domain died, Mitsumasa exchanged Tottori for Okayama and the clan chieftaincy. Ikeda Tadao's son, Ikeda Mitsunaka became
daimyō of Tottori at the age of two, and his descendants would continue to rule the domain to the end of the Edo period. Although the Ikeda clan of Tottori was reduced to a branch of the clan, it was Ikeda Tadao's lineage which was in direct descent from Ikeda Terumasa and Tokugawa Ieyasu's second daughter,
Tokuhime, so the Ikeda clan of Tottori was regarded by the
Tokugawa shogunate as a
kunimochi daimyō clan independent of the head of the Ikeda family of Okayama Domain. In addition to being allowed to use the honorific surname
"Matsudaira", the Tottori Ikeda were also allowed the use of the Tokugawa family crest, as well as being formally recognized as Tokugawa relatives (
shinpan. Normally, when a
daimyō entered
Edo Castle, he had to leave his sword with a retainer in front of the entrance. In addition to the Tottori Ikeda family, the privilege of retaining one's sword was granted only to the Kaga-
Maeda clan and the Tokugawa clan's closest relations, which were the Tottori-Ikeda clan, the
Aizu-Matsudaira clan, and the Echizen-Matsudaira clan. The domain maintained a secondary castle at
Yonago, and ''
jin'ya'' in other important towns within the domain, such as
Kurayoshi,
Yahashi,
Matsuzaki, and
Uradome. The domain suffered greatly from the
Tenpō famine from 1833 to 1837. During the
Bakumatsu period, the 12th
daimyō,
Ikeda Yoshinori, was the older brother of the 15th
Shogun,
Tokugawa Yoshinobu and had a difficult position between loyalty to the shogunate and the growing forces for the
Meiji restoration. Within the domain, conflicts between the loyalists and the pro-Tokugawa factions were intense, and in 1863, an assassination of a senior vassal of the pro-shogunate faction occurred at Honkoku-ji in Kyoto. In the following year, when
Chōshū Domain, with which he had a close relationship, was defeated in the
Kinmon Incident and was declared enemy of the crown, he began to distance himself from politics, but in the
Battle of Toba-Fushimi in 1868 and the
Boshin War, he was on the side of the Meiji government army. As a result, he led the clan's forces in various battles. He was awarded 30,000
koku by the new
Meiji government. The domain became part of Tottori Prefecture with the
abolition of the han system in 1871. Ikeda Terutomo, the 15th chieftain of the clan, was made a
marquis in the
kazoku peerage in 1884. ==Holdings at the end of the Edo period==
