Terran Wars of 1914-1918 (Great War) (as noted and called by the general including those from outside the planet) was the global war that lasted from 13 May 1914 to 14 December 1918. Contemporaneously known as the
Great War or
Weltkrieg or "the war to end all wars" where it led to mobilization of over 79 million people which includes 61 million Europeans, making it one of the largest wars in the history of the planet. It is also one of the deadliest conflicts in history with an estimated 14.2 million combatant deaths with overall 9 million civilian deaths as a direct result of the war, while resulting genocides and the related 1917-1918 Winter Flu pandemic caused another 75-120 million deaths worldwide, including 2.40 million Winter Flu deaths in Europe, 3.03 million deaths in South America and the Insular Atlantic, and overall 3.61 million deaths in Asia-Pacific region.
On 13 April 1914, where two Argentine tourists were also detained by Andean border forces which heats up, leading to Pacific Crisis where Argentine has cut off lithium and silver supplies to the Andean Confederation as well as openly support for Chilean separatists while Andean Confederation responded by cutting off gold, copper, zinc, and mineral trade which worsens the crisis and in East Asia, a looming Korean/Joseon succession crisis ensues with the pretender Prince Imperial Ui with strong Ning preference, leading up to Korean Succession Crisis and as the crisis had reached into Europe when the crisis in Balkan goes from hot to breaking point as the Russians have rallied in support of the Byzantine Greeks, Serbs, and the Bulgarians in response to Ottoman ultimatum to abandoned their claims in Rumelia region. By April of 1914, a great powers of Europe and Asia were divided: The Fifth Power Alliance, consisting Germany, Austria-Hungary, Ottoman Empire, Ning's China, and the Andean Confederation. The Quadruple Entente consists of France, Britain, Russia, and Japan while in Italy, it wasn't realized until in 1915 when an Italian nationalist assassinated Austro-Hungarian heir Archduke Franz Ferdinand in Pula, leading to April Crisis. In response, Austria-Hungary issued an ultimatum to Italy on 08 of April. Italy, then refuses to comply and moved into war-footing by joining the Quadruple Entente while issuing ultimatum to Austria-Hungary, demanding to demobilise and withdraw the investigation which the Austria-Hungary refuses. China also sends ultimatum to Russia, demanding withdrawal of troops and drop the support for the independence of Uyghurs and Mongolians while China is also demanded Japan to back down and give power to Prince Ui in Korea. When both Russia and Japan failed to comply, China officially declares war on both on 20 May while the Ottomans, Austro-Hungarians, and the Germans are rallying in support of China; the latter following suit on 25 May when French starts to mobilisation in support of Russia and Japan while also on 30 May, the Andean Confederation mobilises to honor the alliance with the Fifth Power Alliance.
As the war spreads, Germany is initiating strategy for war on two fronts against France and Russia was to rapidly concentrate the bulk of its army in the West to defeat France within 6 weeks, then shifting its forces to the East before Russia could formally mobilise, same as China as the Chinese forces under the bulk of seven million to be concentrated in an effort to force Russia to accept the defeat. On 5 June, Germany demands free passage over the Netherlands, in hopes of achieving quick victory against France. When the Dutch refuses, the Germans have invaded the Dutch Republic, violating neutrality on 30 May, the British then have declared war on Fifth Power Alliance, signaling the opening into Insular Atlantic front and opening intervention. The Ottoman Empire has entered the war on the side of Austria-Hungary, Germany, and China, opening fronts in Balkan (Rumelia), Sinai, and the Mesopotamia where the Persians have also entered the war on the side of Britain and France, thus spread conflict to the Africa and around the globe. The Entente and its allies have became Allied Powers, while the grouping of Austria-Hungary, Andean Confederation, China, Germany, and its allies into Central Powers.
The Germans advance into France was halted at Tillburg in the late 1914 but successfully driven out and the Chinese attempts to drive Russians at Blagoveshchensk in the early 1915 in which in turn the Western Front and the East Asian Front settled into the war of attrition, marked by long series of trench lines that changed little while the Chinese campaign in Korea has led to defeat of Qing Manchuria and provoking the country into civil war that led to deadly battleground while the Chinese had quickly seized its European possessions such as Hong Kong, Macau, and Guangzhouwan. In the Andes, the Andean Confederation has marked by greater success on Tucuman Front. While in parts of Latin America, Grand Para officially entered the war on the side of Central Powers while Willemine-Mauritius declared war after honoring its alliance with the colonial overlord, the Netherlands in hopes of sending troops to assist the Argentine forces on the Andes Front while Brazil declared war on late 1917 which led to Southern Cone Campaign into Southern American Campaign as the battle fronts have completely expanded overnight. The United States initially remained neutral but became important supplier of war material to Allies and Virginia had declared war on Central Powers in the mid-1917, sending countless of troops while both same as important supplier.
Serbia had officially knocked out in the late 1915 while Bulgaria had continued to fight on until the early 1918 when they signed the peace treaty with status quo. The 1917 January Demonstrations has led to harsh crackdown on protesters, further making easier for Central Power forces to drive into the deeper part of Russia where the continuous discontent amid rising cost of war has forced the Emperor Nicholas II to hold the constitutional referendum that led to February Riots wherein the Russia retains monarchy until on October where Bloody Strikes has led to assassination of Nicholas II, leading to March to Alyeska where members of the imperial family has been exiled to the colony while the new convention holds in Patsifistov[1] where the republic is proclaimed, the proclamation of Soviet Socialist Republic in the European parts of Russia, and the signing of Treaty of Frankfurt by the new government, ending Russia's involvement in war while in South America, the Road to Andes offensive begins with hundreds of freshly conscripted soldiers from the general populace plus with additional reinforcement from the Britain and other colonies and dominions as well as Brazilian troops has quickly driven the Andean forces out from Santiago in harsh attrition from the early 1917 until the mid 1918 and continued successful battles has led to War of the Confederation where Chilean separatists had proclaimed the eventual independence and subsequent collapse of Andean Confederation and while the Japanese, spearheaded by the British, French, and Freycinetia has initiated the Jungle Campaign that successfully driven large numbers of Chinese forces out from Indochina while the Japanese had successfully paralyzed the numerous warships in the Battle of Formosa Strait with the battles in the Korean Peninsula was broken by pro-Japanese Sunjong loyalists in the Battle of Hanseong. With its some allies defeated, revolution at home, and others are exhausted, Britain, France, Japanese, and Germans as well as Chinese had signed the Treaty of Berlin and Osaka, ending its fighting.
Second International War was a significant turning point in the political, economic, cultural, and social climate of the planet. The war and its aftermath has led to Great Crisis of 1916-1924. Defeated powers imposed with status quo with smaller but medium territorial and colonial gains plus with light to medium restrictions placed and the Treaty of Osaka has led to compromise but Allied powers have retained its possessions in China and recognized Sunjong as Emperor of Korea but the Russians have also demanded the independence until a pragmatic compromise terms. As a result of war, the Russian Empires has been ceased to exist, creating new states created from their remains while China has been downsizing its territories and a third international war just followed twenty years later.
