The Warring States of Japan is an umbrella term that covers a 150 years long period of japanese history, starting with the Ōnin War in 1465 with the birth of Ashikaga Yoshihisa and ending with the death of Toyotomi Hideyori in 1615. During this period the government of Japan was severely weakened, which allowed state governors or dukes known as daimyō to gain an unprecedented level of independence. This had the unavoidable consequence of hindering the government's ability to curtail their growing ambition which led to many wars over the control of territories and personal feuds. Notable figures during this period include Oda Nobunaga, Toyotomi Hideyoshi, Tokugawa Ieyasu, Sanada Yukimura, Takeda Shingen, Uesugi Kenshin and many more.
