Tokugawa Ieyasu

1543-1616; Japanese Warlord

At birth the son of a minor daimyo (warlord), in death canonized by imperial decree as Toshodai-gongen, a Buddhist avatar, this one-time subordinate ally of first Oda Nobunaga and then Toyotomi Hideyoshi accomplished what neither of his senior partners had achieved: institutionalizing his power in inheritable form and founding a dynastic military government that endured for nearly three centuries.

Ieyasu capped a military career that spanned six decades with a victory in the Battle of Sekigahara in 1600 that left him in effective control of the nationwide political confederation that Hideyoshi had forged. Nevertheless, although undeniably a shrewd politician, an exceptional general, and an insightful administrator, he owed his lasting success not to superior ability in any of these areas over Nobunaga or Hideyoshi, but to personal longevity and judicious institutional borrowing. Born within a decade of his erstwhile overlords, he outlived Nobunaga by thirty-four years and Hideyoshi by eighteen. He modeled his army and administration largely on those of his most dangerous enemy, Takeda Shingen (whom he also outlived), and further shaped his national regime around policies introduced by Nobunaga and Hideyoshi.
