Takeda Katsuyori

Katsuyori became the head of the Takeda clan after the death of his father, Takeda Shingen. He inherited a powerful domain but faced challenges from Oda Nobunaga and Tokugawa Ieyasu.

Katsuyori led the Takeda army against Oda Nobunaga and Tokugawa Ieyasu at the Battle of Nagashino. His forces were decisively defeated by Nobunaga's use of arquebusiers behind palisades, leading to the loss of many key Takeda commanders.

Katsuyori was defeated by Oda Nobunaga and Tokugawa Ieyasu at the Battle of Tenmokuzan. He committed seppuku, and the Takeda clan was destroyed, ending their influence in the Sengoku period.
