After the
Battle of Sekigahara in 1600,
Asano Yukinaga, the lord of
Kai Province, was granted
Kii Province. This led to the establishment of the
Kishu Domain, which governed the
Asano clan of Tozama. However, in 1619, the
Asano clan was relocated to the
Hiroshima Domain in
Aki Province under the leadership of
Fukushima Masanori. At the same time,
Tokugawa Yorinobu, the tenth son of
Tokugawa Ieyasu and the former lord of the
Sunpu Domain, merged the former territory of Asano with 555,000 koku. This expansion included
Minami Ise and Kishu, which was the main domain governed by the Kii-
Tokugawa clan. As a result, the domain was officially established.
Tokugawa Yorinobu recruited
Rōnin and raised suspicions during the
Keian Incident in 1651, allegedly challenging the
Shogun.
Tokugawa Tsunanori, Yorinobu's grandson and third lord of the domain, married
Tokugawa Tsuruhime, the eldest daughter of the fifth shogun, but died prematurely.
Tokugawa Yoshimune, Tsunanori's younger brother and 5th lord of the domain, became the 8th Shogun after a series of events, bringing over 200 feudal retainers from the Kishū clan to Edo.
Tokugawa Munenao, the sixth lord of the domain, who inherited the clan from the branch domain after leaving Yoshimune, overcam the financial difficulties caused by the
Kyoho Famine, which lost 57% of the amount of the amount of koku, with 20,000 ryo of public money borrowed, but after that, he followed the way to make up for this budget deficit with public money. The Wakayama Domain deepened its financial dependence on the shogunate because it was close to the Shogun, and on the other hand, this became a factor that put pressure on the shogunate's finances. The 11th lord of the domain,
Tokugawa Nariyuki, lost his worship debt during the
Tenmei era, and borrowed a new 20,000 bale from the shogunate's Osaka
Kurazumemai. The balance of the debt reached 45,000 ryo. Keifuku, the 13th lord of the domain, was the grandson of the 11th Shogun
Tokugawa Ienari, and in 1858, he inherited the Shogun family after Iesada, the 13th Shogun without children, and became the 14th Shogun Iemochi. All the successive shoguns after the 8th Shogun Yoshimune were occupied by the Kishu Domain and the
Hitotsubashi-Tokugawa family, which was a branch of it. Following the
abolition of the han system in July 1871, significant changes occurred in the administrative divisions of Japan. The territories of Kishū,
Tanabe, and
Shingū were transformed into separate entities known as
Kishū Prefecture,
Tanabe Prefecture, and Shingū Prefecture, respectively. However, these prefectures were short-lived as they were dissolved in November of the same year. This dissolution led to the establishment of the present-day
Mie and
Wakayama prefectures, which continue to exist to this day. == List of daimyo ==
