Kobayakawa Hideaki was a young daimyo who joined the Western Army during the Battle of Sekigahara.
Kobayakawa Hideaki was born of the Kinoshita family, but was adopted by Kobayakawa Takakage, who ceased to be a member of the Mori Clan. Hideaki served under Toyotomi Hideyoshi in his conquests, and fought in Korea. However, he lost his lands in Chiguko after reckless actions in the Battle of Keicho in the Second Japanese Invasion of Korea in 1598. The same year, Hideyoshi died. When Tokugawa Ieyasu disrespected the authority of the seven year-old son of Hideyoshi, Hideyori, Hideaki sided with Ishida Mitsunari in the power vacuum struggle that culminated in the Battle of Sekigahara. Rumors spread that since Mitsunari insulted Hideaki repeatedly, that he might defect. Otani Yoshitsugu thus placed his troops on the left flank of the Kobayakawa Clan forces. Neither Hideaki nor Shimazu Toyohisa stepped into the battle, and the former defected to the Tokugawa Clan army after Ieyasu coaxed him into the battle with a volley of gunshots. Hideaki changed sides, and struck Mitsunari from the flank. Ieyasu won the battle with the aid of Hideaki and men of the Mori Clan who changed sides as well. Hideaki died in 1602. A year later, Ieyasu was declared shogun and set up the Tokugawa Shogunate (1603-1868).
