The Carlosian War (Verdean La Guerra de Emperador Carlos, Isarléan Le Guerre d'Empereur Charles, Valdens Der Karlkrieg), also known as the First Meridonian Great War, was a seven year and one month long war fought between the Isarlo-Verdean Alliance, led by the Second Verdean Empire and the Triple Pact of Trelein, Valden, and Sumaaväa, over several territories along the coastline of eastern Meridon, most notably, the provinces of San Lumen, and Roslinburg, which were historically Verdean colonies taken over by the mainland powers during the Imperial Period, but that the First Verdean Empire, and successor regimes never ceded claim to. The conflict was immediately sparked by the sabre-rattling declaration of intent to retake lost territories, made by Verdean Emperor Carlos XII Parisa, and the subsequent invasion of Treleini San Lumen.

On May 6th, 1865, The Verdean Imperial Navy formally declared war on the Divine Imperium of Trelein, preparing an invasion of San Lumen twenty days later. The Verdeans unleashed a number of secret weapons during the opening phases of the war, devastating the outdated Treleini military, and quickly seizing victory over Trelein over the course of a few months.

The Verdean Empire subsequently invaded Valden which proved a more lasting conflict; with campaigning in Valden proper lasting nearly three years, before the capital; Weissburg was seized. The Valdens however, refused to surrender, even as the Verdeans launched their ill fated first invasion of Borealés del Norte, then the Sumaaväan capital of Viime Satama. Coupled with the re-entry of Trelein into the war with their new puppet state of Los Cuarzos, as well as the alliance between Isarlé and Verde the war entered it's second phase; as the two alliances fought the bloodiest battles of the war.\

The turning point of the war ultimately came with the disastrous failure of the second invasion of Sumaaväa, and the near complete destruction of the entire army sent to take Viime Satama; with the collapse of that front, and the freeing up of Sumaaväan reserves; 1870 and 1871 saw the complete collapse of the fronts in mainland Meridon, and exit of Isarlé and the Vale from the War; and after the campaign to liberate Los Cuarzos; the death of Emperor Carlos XII, and some campaigning in the Verdean Archipelago proper, the war was end by an armistice on the 31st of December (52 de Mesvacío) of 1871 (DI 71), with the conflict formally coming to a conclusion with the Treaty of Corazón del Río the following year.

The Carlosian War saw the dramatic re-balancing of power in Meridon; with the Verdeans permanently losing their claims to the Mainland, and losing power and influence more generally; seeing the modernization Trelein, paving the way for Capisarian re-unification a few decades later; and establishing Valden became the preeminent continental power until the end of the Valden War in the 1930s.
