The Great War, also known as the World War, the Six Years' War, or the Transmedan War, was a global conflict fought between the Transmedan and Sydenham Powers from 17 April 1934 until 20 October 1940. The conflict saw fighting on every continent and directly involved a majority of the world's nations, including all of the great powers. The war was the first to see the widespread employment of mechanized and aerial warfare by its combatants, and was the last major conflict to take place between great powers before the dawn of the atomic age. More than 50–63 million people were killed during the war, making it one of the deadliest military conflicts in history. The Great War ended with the unconditional surrender of the Sydenham Powers and their occupation by the victorious Transmedan Powers.

The decades preceding the Great War were marked by the global rise of political extremism, with revolutionary nationalist movements taking power in Asplinist Falland, Nadauro, Ruthen, and Razan. By the end of the 1920s, these nations had consolidated into an unofficial geopolitical bloc that challenged the primacy of the era's dominant powers, including Waldrich and the Free States. In the Western Hemisphere, hostilities began with the Fallish invasion of Cuthland on 17 April 1934, followed by the Razanite invasion of X several days later. After pushing Waldish forces out of Cuthland with the Battle of X, Falland launched a full scale invasion of mainland Waldrich in the spring of 1935. Despite rapid success during the first several months of the invasion, the onset of winter caused the Fallish offensive to slow and ultimately stall as the conflict decayed into a war of attrition. Falland and Razan launched concurrent offensives during the summer of 1936 in an attempt to break the stalemate, but both failed to achieve their stated objectives.

In 1937, hostilities began in Elia Australis when Nadauro, supported by Falland and Razan, invaded X while aiming to dominate the Elias and the Elia-Alconian (Esfera legítima). The Sydenham Powers hoped to cut off Waldrich and its allies from valuable natural resources in Elia Australis, which were critical to the Transmedan war effort. The invasion prompted the Free States to join the Transmedan Powers, sending expeditionary forces to both the Waldish and X fronts. By late 1938, Sydenham forces were on the retreat in Waldrich, Hylasia, and X. Nadauro conquered much of Elia Australis but was forced into retreat following the repulsed invasion of the Free States; The Transmedan powers gained naval supremacy in the Medan Ocean during the 1939 Battle for the Medan, allowing the unhindered flow of Transmedan soldiers and supplies between Calesia and the Elias. Falland evacuated its last forces from mainland Waldrich in August, and Transmedan forces liberated Cuthland in October. After the loss of Cuthland, Falland offered to conditionally surrender in an effort to avoid a Transmedan invasion. These overtures were rebuffed by the Transmedan Powers, who demanded the resignation of the national syndicalist government.

In addition, the Transmedan landings at Yecahual and the subsequent capitulation of Nadauro in early 1940, following Cabral's suicide, allowed the Free States and X to shift their war efforts entirely to the Western Hemisphere, providing the Transmedian Powers with additional forces for a prospective invasion of Falland. Transmedan forces ultimately carried out of full scale invasion in May, prompting the overthrow of the national syndicalist regime in a royalist coup d'état and unconditional surrender of Falland less than one month later. The wartime Razanite government was similarly overthrown in October as Transmedan forces entered into Razan proper, bringing an end to the conflict.

The Great War was a political, economic, cultural, and social turning point for the world. It is generally considered to mark the foundation for the contemporary international order, precipitating the dissolution of multiple influential states and the deterioration of others. The United Congress was created to foster international diplomacy and peace, with the Big Three becoming permanent members of its Security Council. In the conflict's aftermath, many of the victorious powers experienced a post-war economic boom which lasted until the early 1970s, but also the decolonisation of Hylasia.
