Fifth Shinobi World War

The Fifth Shinobi World War was an event that took place some 20 years after The Great Shinobi Schism. It was the last world war to occur between all five of the Five Great Shinobi Countries. It led to a state of total war, where all resources both military and civilian were used to fuel the efforts of the war. It was the deadliest conflict in known shinobi history, as it saw the development and use of the Relic Weapons, which were super-weapons created from the remains of The Last God, Itoku.

The war started in September the 1st, 110 A.N when Sunagakure first annexed the Land of Rivers and claimed its industry and resources. Although this was only part of a series of connections that would eventually lead to all-out war between all known shinobi countries.
