Second Hundred Year War (Earth-3813)

The Second Hundred Year War was the second great war between the majority of the bending countries on Earth. Born from the scars and catasthrope of Fire Lord Sozin's first incited conflict, the Second Hundred Year War proved to be the worst conflict in history, claiming hundred of millions of lives. They mostly took place in minor countries, such as the Land of Storms, which left them devastated and effectively broken after the end of the war. Although no official winner was declared, the Fire Nation was the most favored and least affected among the five great nations.

Background
The Hundred Year War ended in 122 AG with the death of Fire Lord Sozin and an armistice treaty, but left the five great nations extremely weakened and economically broken. The treaty ensured an uneasy period of relative peace, but thirty years later, the economic and social disparity between the nations became violent. Factions were formed, and under the pretext of expending rights, the countries started to form their own militaries to expand to neighbour territories, starting a new war which, like the first, would last a total of one hundred years. It was during this time that the Earth Kingdom and the Fire Nation upgraded and increased their military force to become the present war machines they are known to be.
