Answer:
Born to a minor warlord in Okazaki, Japan, Tokugawa Ieyasu (1543-1616) began his military training with the Imagawa family. He later allied himself with the powerful forces of Oda Nobunaga and then Toyotomi Hideyoshi, expanding his land holdings via a successful attack on the Hojo family to the east. After Hideyoshi’s death resulted in a power struggle among the daimyo, Ieyasu triumphed in the Battle of Sekigahara in 1600 and became shogun to Japan’s imperial court in 1603. Even after retiring, Ieyasu worked to neutralize his enemies and establish a family dynasty that would endure for centuries.
