[[Mōri Motonari]] was a ''sengoku daimyo'' who pacified the [[Chūgoku region]] and is famous for his parable of the "Three Arrows", which explains the importance of clan unity. In his first battle, the [[Battle of Arita-Nakaide]] in 1517, he defeated the overwhelming majority of the Aki-Takeda clan with a small force, which later became known as the "[[Battle of Okehazama]] in the West" as a battle in which a small force defeated a large army. Motonari became head of the [[Mōri clan]] in 1523 at the age of 27. The [[Amago clan|Amago]] and [[Ōuchi clan]]s were sharing power in the Chūgoku region at the time, and he switched the Mōri clan's allegiance from the Amago to the Ōuchi clan in 1525. Motonari destroyed the Takahashi clan by 1535 and ruled [[Aki province]], [[Iwami province]], and [[Bingo province]], and destroyed the Aki-Takeda clan at the [[Siege of Koriyama]] in 1541. Motonaga adopted his sons into the [[Kikkawa clan]] and [[Kobayakawa clan]]s to expand the power of the Mōri clan, and the three clans cooperated with each other. In 1554, Motonaga became independent of the Ōuchi clan, and after inciting the Ōuchi clan to internal divisions through political maneuvering, he defeated [[Sue Harukata]], who had been in control of the Ōuchi clan, at the [[Battle of Itsukushima]] in 1555, and defeated [[Ōuchi Yoshinaga]] in 1557, destroying the Ōuchi clan and pacifying Nagato and Suou provinces.
Motonari destroyed the Amago clan at the [[Siege of Gassantoda Castle]] in 1567, and then pacified [[Izumo province|Izumo]], [[Oki province|Oki]], and [[Hōki Province|Hōki province]]s, thus pacifying the Chūgoku region, and later extended his power to parts of [[Shikoku]]. He died in 1571 at the age of 75.<ref name="kotomori">{{cite web|url=https://kotobank.jp/word/%E6%AF%9B%E5%88%A9%E5%85%83%E5%B0%B1-16902|archive-url=https://web.archive.org/web/20240317022808/https://kotobank.jp/word/%E6%AF%9B%E5%88%A9%E5%85%83%E5%B0%B1-16902|script-title=ja:毛利元就|language=ja|publisher=Kotobank|date=|archive-date=17 March 2024|access-date=17 April 2024}}</ref><ref name="toukenmori">{{cite web|url=https://www.touken-world.jp/tips/8100/|archive-url=https://web.archive.org/web/20240417075126/https://www.touken-world.jp/tips/8100/|script-title=ja:毛利元就の歴史|language=ja|publisher=The Nagoya Japanese Sword Museum Nagoya Touken World|date=|archive-date=17 April 2024|access-date=17 April 2024}}</ref>
