**World War I** or the **First World War**, often abbreviated as **WWI** or **WW1**, was a major global conflict that began on 28 July 1914 and ended on 11 November 1918. Referred to by contemporaries as the "**Great War**", its belligerents included much of Asia, the Chinese Empire, the United States, and the Kharo Empire, with fighting taking place across Asia, the Middle East, Africa and parts of Europe. New technology, including the recent invention of the airplane, trench warfare, and especially chemical weapons made it one of the deadliest conflicts in history. An estimated 9 million soldiers died in combat, with another 5 million civilian deaths as a result of military actions, hunger and disease. Millions more died in genocides within the Kharo Empire and the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war.

By 1914, the Asian great powers were divided between the Triple Entente, comprising Indonesia, China, and Marege, and the Triple Alliance, containing Japan, Okinawa, and India. Tensions in Indochina came to a head on 28 June 1914 following the assassination of Crown Prince Yasuhiko Asaka, the Okinawan heir, by Kāwrī Cêāchāy, a Laotian Thai. Okinawa blamed Siam, which led to the July Crisis, an unsuccessful attempt to avoid conflict through diplomacy. China came to Siam's defence following Okinawa's declaration of war on the latter on 28 July, and by 4 August, the system of alliances drew in Japan, Indonesia, and MArege, along with their respective colonies, although India remained neutral. In November 1914 the Kharo Empire, Japan, and Okinawa formed the Central Powers, while in April 1915, India joined Marege, Indonesia, China and Siam as the Allies of World War I.

Facing a war on two fronts, Japanese strategy in 1914 was to concentrate its forces on defeating Indonesia in six weeks before moving them to the Northern Front and doing the same to China . However, the Japanese offensive in Indonesia failed to achieve this and by the end of 1914, the two sides faced each other along the Southern Front, a continuous series of trench lines stretching from the Arafura Sea to Singapore that changed little until 1917. By contrast, the Northern Front was far more fluid, with Okinawa and China gaining, then losing large swathes of territory. Other significant theatres included the Middle Eastern Theatre, the Indian Front, and the Indochinese Theatre.

By the end of 1915, both China and Okinawa had suffered enormous casualties in the North, while Allied offensives against the Kharo and on the Southern Front ended in failure. A major Japanese attack on Manado in 1916 and a Marege offensive on the Kokoda Trail also achieved little other than large numbers of casualties on both sides, while a Chinese offensive in the North ground to a halt after some initial success. By early 1917, China was on the verge of revolution while the failure of the 1917 Umar Offensive and equally costly Marege attacks in Sumatra meant by now all sides were increasingly short of manpower and subject to economic stress.

Shortages caused by the Allied naval blockade had led Japan to initiate unrestricted submarine warfare in early 1917, bringing the previously-neutral United States into the war on 6 April 1917. In China, the Duōshùrén seized power in the 1917 October Revolution and exited the war with the March 1918 Treaty of Kijŏngdong, freeing up a large number of Japanese troops. By transferring these to the Southern Front, the Japanese General Staff hoped to win a decisive victory before the arrival of significant Anokian reinforcements and took the offensive in March 1918. Despite initial success, it was soon halted by heavy casualties and ferocious defense; in August, the Allies launched the Hundred Days Offensive and although the Imperial Japanese Army continued to fight hard, it could only slow the advance, not stop it.

Towards the end of 1918, the Central Powers began to collapse; the Kharo signed an armistice on 31 October, then Okinawa on 3 November. Isolated, facing the Japanese Revolution at home and a military on the verge of mutiny, Emperor Taishō abdicated on 9 November, and the new Japanese government signed the Armistice of 11 November 1918, bringing the conflict to a close. The Jakarta Peace Conference of 1919–1920 imposed various settlements on the defeated powers, with the best-known of these being the Treaty of Bandung. The dissolution of the Chinese, Japanese, Kharo, and Okinawan empires led to numerous uprisings and the creation of independent states, including Korea, Tsushima, and Indochina. For reasons that are still debated, failure to manage the instability that resulted from this upheaval during the interwar period ended with the outbreak of World War II in September 1939.
