Koizumi Domain

The Koizumi Domain (小泉藩) was a Japanese domain of the Edo period, with its headquarters within the city limits of present-day Yamato-Kōriyama, Nara. It was ruled for the entirety of its history by the branch of the Katagiri family founded by Katagiri Sadataka, a younger brother of the famed Katagiri Katsumoto. In July 1871, with the abolition of the han system the Koizumi Domain became Koizumi Prefecture, and later it was finally made a part of Nara Prefecture.



History
The founder of the Katagiri clan was Katagiri Sadataka, the younger brother of Katagiri Katsumoto, who was famous as one of the Seven Spears of Shizugatake. Sadataka and his older brother served Toyotomi Hideyoshi and achieved military exploits in the Odawara conquest and the Bunroku campaign, and were given a fief of 10,000 koku in Harima Province. Sadataka supported the Toyotomi family after Hideyoshi's death, along with his older brother Katsumoto, who became Hideyoshi's vassal.

After the Battle of Sekigahara in 1600, Sadataka had his fief transferred to Yamato-Koizumi 10,000 koku by Tokugawa Ieyasu. This was the establishment of the Katagiri clan. In the wake of the Hokoji Temple Bell Mei dispute that occurred in 1614, the Katagiri brothers were suspected by Hideyori and others of secretly communicating with Ieyasu, and Sadataka withdrew from Osaka Castle with Katsumoto and moved to Settsu Ibaraki. Moved to the castle. It is said that when evacuating from Osaka Castle, 300 soldiers of the Katagiri clan were fully armed and made a spectacular move by lighting the matchlocks of their guns. The Toyotomi family lost its pillar, the Katagiri brothers, and was destroyed by Ieyasu in the Osaka Siege that began in the same year.

After the Siege of Osaka, Sadataka became a vassal of Ieyasu and received an increase of 6,000 koku, bringing the Koizumi domain to 16,000 koku.

The second lord of the domain, Sadamasa Katagiri, who was Sadataka's son, was well-known as a tea master and was known as ``Katagiri Sekishu. In 1665, he became a tea ceremony instructor to the shogun Tokugawa Ietsuna, establishing the Sekishu style of tea ceremony. He is also a person with many accomplishments in the field of architecture. Sadamasa distributed 3,000 koku to his younger brother Katagiri Sadharu, so the Koizumi clan had 13,000 koku.

When Sadayasa's third son and third lord, Katagiri Sadafusa, distributed 1,000 koku to his illegitimate brother, Katagiri Nobutaka, the total amount was 12,000 koku. Afterwards, he was given an additional 1,000 koku, bringing his total koku to 11,000 koku.

The fifth lord of the domain, Katagiri Sadane, was punished by the shogunate for his clumsiness. The 8th lord of the domain, Katagiri Sadanobu, was a tea master known as Shunsai, and is said to be the founder of the Sekishu style of Chuko.

At the end of the Edo period, a number of feudal lords died early, so the 11th lord, Katagiri Sadatoshi, was adopted by another family. However, his adopted children also died young one after another. The end of the Edo period came during the era of Teiatsu Katagiri, the last feudal lord. Sadaatsu was a member of the Mito Tokugawa family, and was initially a member of the Sabaku faction, contributing to the subduing of the Tenchu-gumi, but during the Boshin War in 1868, he cooperated with the new government and defended Kyoto.

He became the governor of the Koizumi domain in 1869 when the domain was restored, and in 1871 when the domain was abolished and the prefectures were established, he was relieved of his post as governor, and the Koizumi domain was abolished.
