Iyo Province

Iyo Province was formed by the Ritsuryo reforms by combining the territories of the {{nihongo|Iyo-no-kuni no miyatsuko|伊余国造||}}, who ruled a territory centered on what is now the city of Iyo and town of Masaki with Kumi Province, Kazehaya Province, Touma Province, and Koichi Province each ruled by its own kuni no miyatsuko. The Geiyo Islands in the Seto Inland Sea were considered part of Aki Province into the Edo Period. During the Heian period, the coastal areas of the province were part of the stronghold of Fujiwara no Sumitomo, who led a rebellion against Imperial authority. During the Muromachi period, a branch of the Saionji family was appointed as shugo by the Ashikaga shogunate, but was constantly being invaded his more powerful and aggressive neighbors. The Saionji survived by the fluid loyalties and fierce resistance, but were eventually overcome by Chōsokabe Motochika, who was in turn overthrown by the forces of Toyotomi Hideyoshi. {{cite book |last1=Nakayama |first1=Yoshiaki |title=江戸三百藩大全 全藩藩主変遷表付 |date=2015 |publisher=Kosaido Publishing |isbn= 978-4331802946}}{{in lang|ja}} Under the Tokugawa shogunate, the province was divided into several feudal domains.
