Great War

The Great War, also referred to simply as The War, was a significant conflict that occurred on Remnant, the being between the Kingdoms of Vale and Vacuo on one side and the Kingdoms of Mantle and Mistral on the other side. It came to its conclusion roughly eighteen years ago before the events at the beginning of First Beacon of Darkness.

The Great War preceeded the Faunus Rights Revolution, a conflict over racial politics, by a couple years.

Tensions
In the century leading up to the War, there was high tension between the four kingdoms, mostly caused by Mistral, which had allied itself with Mantle. The two traded frequently, with Mistral sending supplies and Mantle providing insight on how to settle the snowy northern region of Anima. After an incident with the Grimm, Mantle came to believe that, if it abolished the arts and repressed self-expression to control its citizens' emotions, it would be safer from Grimm. Rather than lose its alliance, Mistral complied with Mantle's wishes to an extent, banning the arts and self-expression everywhere in the kingdom except for within its central power. This added to the list of things that Vale disliked about Mantle and Mistral, which included the two kingdom's treatment of their own citizens, their use of slave labor and their insistence that their way of life was what was best for everyone.

Eventually, Mistral and Vale both set their sights on settling the islands and peninsulas on the east coast of Sanus. Despite what his citizens wanted, the king of Vale chose to share the land with the settlers from Mistral.

Outbreak of Conflict
However, the immensely high tensions ultimately resulted in a riot between the two bands of settlers. It was unknown to the world who attacked first, but later it's revealed the hitman Genocide assasinated the king of Vacuo with weapons of Mantle and it began the first battle of the Great War. Mantle quickly came to Mistral's aid, and battles were fought on both Sanus and Anima soil.

For a time, Vacuo remained neutral, due to Mantle and Mistral having established a presence in their territory in the years prior. When the two began pressuring Vacuo to ally with them, the citizens of Vacuo realized that if Vale fell, there would be no one left to stop Mistral and Mantle from conquering them. Vacuo rallied against Mantle and Mistral and pushed them out of the Vacuoan territory and allied themselves with Vale.

Overall, the Great War lasted for three years. Food and Dust rations were put into effect, development of technology accelerated, Humans and Faunus on the battlefield grew closer and Grimm attacks increased worldwide. Whenever the Grimm would invade a battlefield, the armies called a temporary ceasefire long enough to eradicate the monsters, before continuing to fight each other. Many settlements were lost to the Grimm, due to their best warriors being away to fight in the War, and most of those settlements were never reclaimed.

Approximately seventeen years before the beginning of First Beacon of Darkness, the Great War came to an end during the Vacuo campaign, where Mantle and Mistral targeted Vacuo, hoping to cut off their enemy's Dust supply by conquering Vacuo's mines. The king of Vale arrived and personally led his army alongside Vacuo's, thoroughly decimating the opposing forces. It is said that Vale's king, from then on nicknamed the Warrior King, laid waste to countless men on his own, but historians believe that this feat was aided by Vacuo's unusually violent weather patterns and Mantle's inexperience in desert combat. Ultimately, Crystal Corp launched the most deadly weapon of massive destruction, the Nuke Dust Bomb (NDB) and all of the kingdoms decided to stop since that bomb was a part of the Covenant which wasn't allied to a specific kingdom and continue the fight would just lead to the destruction of the fourth kingdoms. What nobody knew was that the NDB was really launched to destroy Sapphire Dust and the end of the Great War was just a secondary effect.

Resolution
Following this battle, the four kingdoms gathered on neutral ground on the island of Vytal, where they formed a treaty and planned the future of Remnant. The leaders redistributed territories, abolished slavery and restructured the governments. The Faunus were given equal rights and were gifted the continent of Menagerie for their own use in order to compensate for their previous mistreatment.

Vale's king founded the Huntsman Academies in each of the four kingdoms; Beacon Academy in Vale, Shade Academy in Vacuo, Haven Academy in Mistral and Atlas Academy in Mantle. He placed his most trusted followers in command of each academy. The intended purpose of the academies was to train Huntsmen and Huntresses, warriors whose sole purpose would be to fight the Grimm, and whose allegiance would not be tied to the kingdoms. Secretly, the academies were also given the task of safeguarding four Relics. Sometime after the end of the Great War, Mantle's capital was moved to Atlas, and the government, military and academy were combined.
