The Great Shinobi Schism

The Great Shinobi Schism is an event that occurred approximately 200 years ago following the death of Naruto Uzumaki, or Itoku, as he was deified upon his death. A conspiracy had developed in the years between four of the Five Great Shinobi Countries, whereas all sought a balance in power between themselves and the Land of Fire since it had procured two of the strongest shinobi within recent history. Itoku's death also brought the temporary death of the Nine-Tails, as he was still sealed in Itoku upon his death. This severely hampered Konohagakure's military power, and in turn the same for the Land of Fire. Before Itoku could be buried, the four rebelling great countries mustered their forces and marched on Konohagakure. The Land of Fire surrendered before too much blood was shed, and a summit was convened to discuss the aftermath of the war. It was there that Itoku's corpse was taken apart and divided amongst the Five Great Shinobi Countries as relics that held immense powers.

However Sasuke Uchiha, or Ōkage as his deified name was, his body could not be found. It was a subject of content at the Five Kage Summit, as it had been suspected that Konoha had hidden the body some years ago. It was this content which would eventually lead up to the Fifth Shinobi World War in a bid to secure the remains of Ōkage.
