Mōri Terumoto
Hiroshima was established on the delta coastline of the Seto Inland Sea in 1588 by powerful warlord Mōri Terumoto. Hiroshima Castle was quickly built, and in 1593 Mōri moved in. Terumoto was on the losing side at the Battle of Sekigahara. The winner of the battle, Tokugawa Ieyasu, deprived Mōri Terumoto of most of his fiefs, including Hiroshima and gave Aki Province to Masanori Fukushima, a "daimyō" who had supported Tokugawa. From 1619 until 1871, Hiroshima was ruled by the Asano clan.
