Among the many conflicts and arcs in Naruto Shippuden, none had a greater impact than the Fourth Great Ninja War. This epic war, spanning hundreds of episodes, saw legendary shinobi, the resurrection of fallen heroes, and a battle for the fate of the world. At the heart of this war was the Allied Shinobi Forces, a historic unification of the Five Great Nations and the Land of Iron against the looming threat of the Akatsuki and the reawakened Madara Uchiha.
