The Sarria War was fought in 1914 between the Gladysynthian Empire and its rebelling northwest territories, Noravia, Sontre, South Thetlia, and Allieu, and nations who sided with the rebellion such as Elbresia and Caspiaa. The Gladysynthian empire controlled much of northwest Euronia from the 15th-19th century, but emergence of democracies throughout Nortua, the increasing abolition of monarchies throughout the world, and Gladysynthia's oppressive policies on its colonies drove nationalist movements in the occupied territories.

After the 1913 D'Olonne massacre, secessionist sentiment erupted and on 2 January 1914, the Gladysynthian governor's residence in Santara was burned by rebels, officially marking the beginning of the war. Within weeks, rebellions broke out across northwest Euronia and eventually a full-fledged multi-front war of independence was underway. Sontre and Noravia allied their various militias against Gladysynthia, while the already independent North Thetlia rallied to liberate its ancestral South Thetlia. The independent Porte-Lyon aligned with the autonomous Elbresian territory of United Allieu to liberate occupied Allieu, and their involvement in the war brought the support of the Elbresian military and Royal Caspiaan Armed Forces. Gradually these factions aligned in common purpose under the Kasuum Alliance, and their coordination allowed for complex military campaigns which resulted in Gladysynthia withdrawing the majority of its military by November of 1914 amid major losses. Gladysynthian emperor Sawin Ardinia signed the Treaty of Sables on 19 November, officially ending the conflict and granting independence to the Kasuum Alliance members.

An estimated 200,000 soldiers and 50,000 civilians died in the war, with the introduction of modern weaponry contributing to high casualties in the clashing of large armies and in the bombardment of cities. The war drastically changed the course of northwest Euronia, as the sudden collapse of Gladysynthia's imperial holdings in the region led to internal conflict within Gladysynthia and its remaining holdings and severely weakened its prominence as a major power in Euronia, emphasized by the First Danaska War and the Gladysynthia Civil War and its withdrawal from the World War. The full independence of Noravia, Sontre, and Thetlia, combined with the unification of Allieu and its eventual full-independence a few decades later, pushed a democratic movement throughout the region even as Thetlia maintained its monarchy.
