Where others conquered, Tokugawa Ieyasu endured. The most patient of Japan’s three great unifiers, he outlasted his rivals, won the final battle for the country, and built an order so stable it lasted for over two and a half centuries.
Sekigahara
Ieyasu was a longtime ally of Oda Nobunaga and then of Toyotomi Hideyoshi. When Hideyoshi died, Ieyasu moved to seize supreme power, winning the decisive Battle of Sekigahara in 1600. In 1603 he took the title of shogun, founding the Tokugawa dynasty that would rule Japan.
The long peace
From his base at Edo — the small town that would grow into Tokyo — Ieyasu built a centralized system that locked Japan into stability and, later, isolation from the outside world. The Edo period he founded brought more than 250 years of peace, an extraordinary stretch in the medieval-to-modern transition. Like William the Conqueror in England, this shogun won power in a single great battle and used it to reshape his nation for centuries.
