上杉景勝
During the Edo period, Aizu was controlled briefly by Uesugi Kagekatsu in 1600 after the death of Gamo Ujisato in 1596. Tokugawa Ieyasu accused Uesugi of gathering troops in Aizu. Ieyasu then transferred the Uesugi to Yonezawa. Through inheritance, Aizu was passed to Hoshina Masayuki (a brother of the third Tokugawa shogun) in 1643. The Edo period saw the economic and cultural growth of Aizu.
