SECTION II -- OVERVIEW
Born in 1543 in Mikawa Province, Ieyasu spent his childhood as a hostage of the Imagawa clan before allying with Nobunaga after Okehazama.He survived every twist of the unification wars, served Hideyoshi as one of the Five Great Elders, and waited.
When Hideyoshi died in 1598, Ieyasu maneuvered the country into the climactic Battle of Sekigahara (1600), where his Eastern Army crushed the Western coalition in a single afternoon.Appointed shogun in 1603, he established the Tokugawa Bakufu in Edo and crushed the last Toyotomi loyalists at the sieges of Osaka in 1614–1615.
The Tokugawa peace he founded — sakoku isolation, sankin-kōtai alternate attendance, the rigid four-class system — endured 264 years until the Meiji Restoration.

SECTION V -- FIELD NOTES
[A]The Patient Warlord
Of the three unifiers, the proverb runs: 'Nobunaga pounded the rice, Hideyoshi cooked it, and Ieyasu ate it.' Ieyasu's patience — outliving rivals across 73 years — secured what the others had merely begun.
SECTION VI -- LEGACY & IMPACT
Ieyasu founded the longest-lasting shogunate in Japanese history. The Tokugawa institutions of sankin-kōtai, sakoku, and class hierarchy shaped Japanese society until the 1868 Meiji Restoration, and many cultural patterns of 'traditional Japan' — from kabuki to ukiyo-e — flowered under the Pax Tokugawa he established.

The most famous ninja in history was almost certainly not a ninja at all. He was a regular samurai officer who happened to lead specialists from a village called Iga — and that fact changes everything about how we should read the legend.

Kamakura vs Edo: Why Two Samurai Governments Failed and Lasted Differently
Japan had three shogunates. Two of them are important.
