SECTION II -- OVERVIEW
Born Nagao Kagetora in 1530, Kenshin took the Uesugi name and the post of Kantō Kanrei from the dispossessed Uesugi Norimasa, becoming one of the most respected daimyo of the era.A devout follower of the war-god Bishamonten, he fought what he called 'just wars,' famously sending salt to his rival Shingen when other warlords had embargoed the Takeda.
His five clashes with Shingen at Kawanakajima made the rivalry legendary.He defeated Oda Nobunaga's forces at Tedorigawa in 1577, the only general ever to do so, and was preparing a march on Kyoto when he died suddenly in 1578 — by some accounts of a stroke in his lavatory, by others poisoned — sparing Nobunaga a second mortal threat in the same decade.

SECTION V -- FIELD NOTES
[A]Salt for an Enemy
When the Imagawa and Hōjō embargoed salt to the landlocked Takeda, Kenshin sent salt of his own, declaring that 'wars are to be won with swords, not with rice and salt' — a gesture remembered as the height of samurai chivalry.
SECTION VI -- LEGACY & IMPACT
Kenshin became the moral archetype of the samurai — the warrior-monk who fought for principle rather than gain. His defeat of Nobunaga at Tedorigawa stands alone in Sengoku history.

Five battles, twelve years, no decisive winner. The story of Takeda Shingen and Uesugi Kenshin's repeated meetings on a single Shinano river plain became, for the Japanese, the archetype of a rivalry between equals.
