1914–1918 global conflict

World War I, or the First World War, also known as The Great War, was a global conflict between two coalitions: the Allies and the Central Powers. Major areas of conflict included Europe and the Middle East, as well as parts of Africa and the Asia-Pacific. The war saw important developments in weaponry including tanks, aircraft, artillery, machine guns, and chemical weapons.

1917–1922 civil war in Russia

The Russian Revolution was a period of political and social change in Russia, starting in 1917. This period saw Russia abolish its monarchy and adopt a socialist form of government following two successive revolutions and a civil war. It can be seen as the precursor for other revolutions that occurred in the aftermath of World War I, such as the German Revolution of 1918–1919.

The United States entered into World War I on 6 April 1917, more than two and a half years after the war began in Austria-Hungary. Apart from an Anglophile element urging early support for the British and an anti-tsarist element sympathizing with Germany's war against Russia, American public opinion had generally reflected a desire to stay out of the war. Over time, especially after reports of German atrocities in Belgium in 1914 and after the sinking of the RMS Lusitania in a torpedo attack by a submarine of the Imperial German Navy off the southern coast of Ireland in May 1915, Americans increasingly came to see Imperial Germany as the aggressor in Europe.
