The Siduri War was a major conflict that lasted from 1934 to 1938. Most of the fighting occurred in the continent of Siduri in the region of Tyran, with several major naval battles occurring in the oceans around the continent. Most countries in Siduri were involved and were formed into two alliances, the Inner Sphere composed of Syara and Allamunnika, and the Common Axis which included Ruvelka, Quenmin, the Cacertian Empire, and Tennai. Both sides mobilized massive military forces and committed humongous levels of natural and industrial resources into the war, resulting in fighting on a scale not seen until that point in Tyran's history.
The war began on 4 April 1934 when Syara and Allamunnika jointly invaded Ruvelka. Despite fierce resistance from the Ruvelkans the country was conquered within two months and subsequently divided and occupied between Syara and Allamunnika. In response to the blatant aggression Tennai and Quenmin signed a mutual defense pact, which the Cacertian Empire later joined to form the Common Axis. Syara and Allamunnika, known as the Inner Sphere, saw Cacerta's entry into the pact as proof of their desire to reinstate their hegemony over Siduri and used it as justification to invade Tennai and Quenmin. After some initial success the Inner Sphere forces were stalled and the war settled into a stalemate. With Cacerta supplying Tennai and Quenmin with resources and mobilizing massive military forces to reinforce the fronts, the Inner Sphere realized they stood to lose a war of attrition. This resulted in the decisive naval engagement known as the Battle of the Sabri Sea which resulted in the decimation of the Inner Sphere fleet. Attempts to regain the initiative on the ground failed as well, and in 1936 the Common Axis launched a series of strategic offensives that forced the Inner Sphere out of Tennai and Quenmin and eventually invaded Allamunnika proper. Costly counterattacks by the Inner Sphere forced the Common Axis back but also depleted both Syara and Allamunnika of resources and manpower. In 1937 the Common Axis invaded Allamunnika again with the Inner Sphere only able to stop the advance after heavy losses.
Faced with a growing shortage of resources and manpower and fearful of further invasions Allamunnika underwent a coup in which the Fascist government was allowed to continue it's existence in exchange for switching sides against Syara, which it did in the summer of 1937. Syara was forced to withdraw it's forces into Ruvelka and attempted to defend it's occupied territories, but the overwhelming material and numerical superiority of the Common Axis defeated the Syarans in the winter of 1937-1938, liberating Ruvelka and forcing Syara to sue for peace.
The war was the most devastating conflict in Siduri history, with nearly 10 million killed or missing and nearly 20 million wounded. The Fascist government in Allamunnika would survive for several more decades but would never fully recover from the conflict. The Cacertian Empire would eventually dissolve thanks in part to the costs of the war which required major mobilization of it's population and industry, while Quenmin would undergo significant internal reform and change. Syara escaped occupation by the Common Axis but was forces to pay the equivalent of $400 billion in war reparations, and the lasting impact of the war is sighted as a major factor in the outbreak of the Refusal War 40 years later. The war was also a major point in the development of military technology, including radios, armored vehicles, aircraft, aircraft carriers, and automatic weaponry.
