Province data
During the Sengoku period, Iyo was divided among the Kōno clan at Yuzuki Castle, the Saionji clan in southern Iyo, and the Iyo-Utsunomiya clan at Ōzu, with further fragmentation caused by the interventions of the Chōsokabe clan and the Mōri and Ōtomo clans. After submitting to the Toyotomi regime during the Shikoku Campaign in 1585, Iyo became divided among several daimyo including Kobayakawa Takakage, Fukushima Masanori, Katō Yoshiaki, and Tōdō Takatora. In the Battle of Sekigahara, the Katō and Tōdō clans, fighting as Eastern forces, retained their domains, and their rule continued thereafter.
