The battle of Sendanno was a battle during the Sengoku period (16th century) of Japan, one of many fought by daimyà Âs (feudal lords) who sought to suppress the anti-samurai uprisings of the Ikkà Â-ikki. The Ikki were mobs of peasants, commoners, monks, and low-ranking samurai who revolted out of a desire to improve their social standing by threatening to overthrow the daimyo.
In December 1536, Nagao Tamekage set out from the castle of Kasugayama to fight against the Ikkà Â-ikki of Kaga Province. They met in battle at a place called Sendanno, in Etchà « Province. There, Tamekage was defeated and killed, along with many other Nagao clan warriors. Tamekage's son, known as Nagao Harukage, was not present at the battle.
