First Barons' War

The First Barons' War was an armed military conflict that was fought in the Kingdom of England from 1215 to 1217. Like several other wars throughout history, it was another theatre of the endless conflict between the Assassins and Templars.

In it, a group of rebellious English barons were supported by the French Army to instigate a civil war against King John after the monach refused to accept the terms of the newly-crafted Magna Carta agreement. However, the war quickly evolved into an attempt by the French prince Louis VIII to gain English lands.

Although Louis managed to seize several English towns during the war, his barons eventually defected back to the English side after King John's death, leaving Louis without support and unable to secure his hold on England. On 11 September 1217, Louis relinquished the ground he had won during the war and returned to France, with the conflict ending in a stalemate.
