Deseleni War
The Deseleni War, also known as the War of the Seleucidae (15 March 2036 - 14 December 2053) was a worldwide conflict that was fought primarily between the newly-formed Allied Security Council led by Quenmin, United Kingdom, Bethausia, Joyonghea, Holy Trabian Empire, Gallia-Bruhl, and Concordia against the newly reformed Resurrected Seleucid Empire that were created by a Seleucid claimant Seleucus I Michael who overthrew the Militesi Emperor and proclaimed the resurrected empire. The war was named after the Deseleni, a global organization whose principal members are the descendants of the Seleucid dynasty, and whom hold noble or upper-class status.
Events that would lead up to the war were the 2034 Eordis Global Famine and the 2034-2036 Protests in Eordis. These events were caused by the 2033 Redstone Eruption which crippled half of North Amerigonna and drastically caused worldwide economic distruption that led to the end of the Neocon War as both sides began to shift to a full mutual cooperation in order to save each nation's economies. The Allied Security Council was formed as an international cooperative organisation aimed to ensure sovereignty in each nations as rebellions and revolts were beginning to take shape between 2034 and 2036. In mid-2035, a Militesian claimant named Seleucus I Michael led a coup and overthrew Militesi Emperor Karl V from the thrown as well as the entire ruling Militesi government. Michael would later proclaim the Resurrected Seleucid Empire, a nod to the ancient Seleucid Empire and declaring absolutism. Other Middle East, Africanna, and Asiannan states would join or align themselves into the new nation.
The ASC would grow concerned as the Seleucids would make their aggression in Africanna and Asianna. However, still reeling from the effects of the past 2 wars and the Redstone eruption, the Allies could not do anything. In the 101st Anniversary of the start of the Second Europan War, the Seleucid and Egypian-aligned Seleucid forces attacked the Estharian controlled Schwarz Canal, that began the war which lasted for 10 years. The course of the Deseleni War saw the Allies losing every inch of land and territory. By 2042, the Resurrected Seleucid Empire had grown to rule nearly 50% of Eordis. However, their shortcomings were beginning to shed by 2043. The Seleucids had become overconfident of winning the Amerigonna territories but as history had told, Amerigonna's distance from Seleucid centres of occupation at Asianna would prove to be biggest mistake that the Seleucids made. Coupled with the attempt to invade Zanarkand, the Seleucids had overstretched their naval forces such that they were unable to wage a naval war on two fronts, despite the assurance that the navy was "more than capable" and had grown to the size twice of the entire Allied Navies.
On the other hand, the Seleucid land forces attempted to invade the Erebonian Empire during their ambitious Operation Anicetus. Their forces would mark their last attempt at another land invasion as the Erebonian Winter stalled the Seleucid Forces on land for the first time in the war, prompting the allies to launch the Allied Winter Counteroffensive of 2042-2043 that began the Allied counteroffensive in Scandinavia. At the same time, the coinciding naval battles at the Zanarkian Sea and on the Concordian Sea saw the Allies defeat the Seleucid Imperial Navy at the same time, as key commanders of the two battles were killed as Allied raiders changed the missile coordinates from the key Allied cities of Washington and Zanarkand, to the two commanding ships. These battles proved to be the turning point of the war, as Allied forces regained momentum and finally continued to push the Seleucids back.
The Liberl Kingdom was the first Seleucid-controlled territory to be liberated by the Allies following the 2044 Allied Invasion of Seleucid Liberl. In the Kakoda Track Campaign of 2043, the Allies prevented the Seleucid's advance to Port Ponsonby, preventing the fall of the Guinea Islands and the isolation of Zanarkand and New Akiba. The Allies began their Island Hopping campaign, using Zanarkand as a springboard for their invasion. The Allies would land on Hindalesia by 2047, securing a crucial point to begin the invasion of Quenmin. By late-2047, the Allies launched Operation Telerium, the Allied Invasion of Seleucid-occupied Quenmin and Bethausia that saw the liberation of the two countries, and the reestablishment of their respective governments in the region.
The Belgen Conference launched by the Allies following the victories would see Lucian Prime Minister Ignis Stupeo Scientia declare that the Allies would accept nothing but Unconditional surrender, which meant that all hopes for the Seleucids to negotiate was dashed.
