Date Masamune

“The One-Eyed Dragon”

Heir of Date Terumune, lord of Yonezawa Castle. He lost his right eye to smallpox as a child and was called "the One-Eyed Dragon." Succeeding at eighteen, he cut his way out of the encirclement at Hitotoribashi, and at Suriagehara in Tenshō 17 destroyed the great Ashina house in a single day, took Aizu and became master of southern Ōshū. But the following year he answered Toyotomi Hideyoshi's summons to Odawara dressed in white, submitted, and saw his dream of expansion cut short by the ban on private war. He sided with the Tokugawa at Sekigahara and Osaka and laid the foundation of the Sendai domain, 620,000 koku. A lover of display whose name gave Japanese the word "date" for a dandy, he was also a man of refinement and enterprise who sent an embassy to Europe. He left the Chinese poem that begins "On horseback the years of youth passed."
