The Ashikaga shogunate required the shugo-daimyō to reside in Kyoto, so they appointed relatives or retainers, called shugodai, to represent them in their home provinces.
During this and other wars of the time, kuni ikki, or provincial uprisings, took place as locally powerful warriors sought independence from the shugo-daimyo.
Those who had failed to exert control over their deputies fell from power and were replaced by a new class, the sengoku-daimyō, who arose from the ranks of the shugodai and jizamurai.
Shōgun Tokugawa Ieyasu reorganized roughly 200 daimyo and their territories into han, which were assessed by rice production.
Several shinpan, including the Tokugawa of Owari (Nagoya), Kii (Wakayama), and Mito, as well as the Matsudaira of Fukui and Aizu, held large han.
[citation needed] Tozama daimyō held mostly large fiefs far away from the capital, with e.g. the Kaga han of Ishikawa Prefecture, headed by the Maeda clan, assessed at 1,000,000 koku.
Other famous tozama clans included the Mori of Chōshū, the Shimazu of Satsuma, the Date of Sendai, the Uesugi of Yonezawa, and the Hachisuka of Awa.
Initially, the Tokugawa regarded them as potentially rebellious, but for most of the Edo period, control policies such as sankin-kōtai, resulted in peaceful relations.
[12] In the wake of the changes, many daimyo remained in control of their lands, being appointed as prefectural governors; however, they were soon relieved of this duty and called en masse to Tokyo, thereby cutting off any independent base of power from which to potentially rebel.
