Tenshō Iga no Ran (天正伊賀の乱; Iga's chaos in the Tenshō Era) also called the Siege of Iga and the Iga Tenshō Revolt, was a devastating battle that happened in 1581 (Tensho 9), involving the Oda Family and the Iga Forces. The event happens in the fiction Pure Heart: Ninjutsu Chronicle.

Ran (乱) also means rebellion/revolt.

AboutEdit

In 1579 (Tensho 7), Nobukatsu Oda (織田 信雄) of Kitabatake family led a unsuccessful invasion on Iga Province. Ridiculing his son, the famous daimyo Nobunaga Oda (織田 信長) sent forty thousand troops (some sources state more) into Iga two years later. It is possible that the reason for the invasion was that Nobunaga didn't trust the ninja[1] or/and that Nobukatsu wanted to build his reputation.[2]. Another possible reason is a so-called accusation of betrayal by a Iga ninja named Kai Shimoyama (下山 甲斐). The Koga would assist the Iga families as well. There were many causalities on both sides; some forces surrendered.

There were three revolts. The first revolt (第一次伊賀の乱), led by Nobukatsu Oda (Also called "Nobuo)", happened in 1579. The people of Iga quickly got wind of Nobuo's plot and he was completely defeated by surprise attacks. The second revolt (第二次天正伊賀の乱) happened in 1581 (Tensho 9) and was the most infamous strike. There was apparently a third revolt (第三次 天正伊賀の乱) in 1582 (Tensho 10) by Iga remnants, who reemerged from hiding and stood in rebellion after Nobunaga's death by the hands of his retainer Mitsuhide Akechi.

Please note, that much of the revolt information below is from the website Taimatsu's iganoran.
