On this day, nearly eighty years ago, the largest war in recorded history came to an end. It was a war of ignorance, of greed, and of oppression. A war that was about much more than where borders fell or who traded with whom, but about the very idea of individualism itself.

The war pitted Vacuo and Vale against Mantle and Mistral.

The Great War, also referred to simply as The War, was a significant conflict that occurred on Remnant, the combatants being between the Kingdoms of Vale and Vacuo on one side and the Kingdoms of Mantle (now Atlas) and Mistral on the other side. It came to its conclusion roughly eighty years before the events at the beginning of RWBY.

The Great War preceded the Faunus Rights Revolution, a conflict over racial politics, by several years. However, no specific time frame has been provided.



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.

Vale vs. Mantle and Mistral

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 is unknown who attacked first, but 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 ten 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 invaded 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.

The end of the war

Approximately eighty years before the beginning of RWBY, 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, it was the deadliest battle of the entire war.


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. Although the Kingdoms were ready to bow before the rule of Vale and it's Warrior King, he decided against it. Instead, 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.[1]

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 the Relics. Sometime after the end of the Great War, Mantle's capital was moved to Atlas, and the government, military and academy were combined. In order to give it's people a beacon of hope, the city was eventually raised into the air using the Relic of Creation, with the "official" story being that it was done using Gravity Dust.

The name of the paper signed to end the Great War is known as the Vytal Peace Accord.[2]

Eventually, Nicholas Schnee wanted to help his home country following the resolution of the Great War and funded an expedition to look for Dust deposits in the Kingdom of Atlas. He managed to fund it using the money he got after his father passed away and eventually managed to find a Dust deposit to start mining. Following this, he founded the Schnee Dust Company while attempting to help the people of the Kingdom and built a positive reputation for the company. However, Nicholas wasn't that great of a businessman and the company was constantly in debt.

Some time later, both the Schnee Dust Company and the Mistral Trading Company mined the Dust deposits in Vacuo and depleted the Kingdom of it's once bountiful natural resource. Because of this, many people in the Kingdom's capital city still resent the other Kingdoms. After the Dust deposits were all depleted, they eventually abandoned many of their Dust refineries in Vacuo, one of them later being used by The Crown as a base of operations.

Later in life, Nicholas' health began to fail and he was convinced by his son-in-law, Jacques Gélé, to let him take over the company which eventually allowed it to prosper at the cost of it's soul. Following his takeover of the company, he began using controversial practices such as abusing Faunus workers and having shady business dealings.


In "Field Trip", Professor Ozpin talks about the War in a speech to an assembly of students from all four kingdoms. He states that the War was the largest conflict in recorded history. Today, Remnant enjoys peace and "unity through diversity". This diversity is celebrated in cultural events such as the Vytal Festival, named after the place where the peace was brokered.[3] Those who opposed the destruction of individualism made it a part of their legacy by naming their children after the fundamental aspect of art, color, to demonstrate that they and future generations would always oppose oppression, a trend that continues into the present era.

The blade passed down through the Arc family line

Jaune Arc reveals in "The Shining Beacon" that his sword and shield, Crocea Mors, were passed down from his great-great-grandfather, who used it to fight in "the War". The simplistic design of Crocea Mors in comparison to other weapons seen in the series may give some clues as to the nature of the weaponry used in the war.

In "A Minor Hiccup", Weiss Schnee explains that in the aftermath of the Great War, the Kingdom of Atlas developed and shared the Cross Continental Transmit System in order to allow the four kingdoms to communicate with one another more effectively.


  • The War provides an in-universe explanation for the "Color Naming Rule" of the RWBY universe. These guidelines, set by Monty Oum,[4] state that all characters and team names in RWBY must have a name that is either a color, sounds like a color, means a color or is otherwise evocative of a color.
