On one side of the war were the [[Central Powers]]: [[Austria-Hungary]], [[Germany]], [[Bulgaria]], and the [[Ottoman Empire]].  The [[Allies]] consisted of the [[Britain|British]] and [[France|French Empires]], the Tsarist [[Russian Empire]](until 1917), [[Italy]], [[Japan]], [[Portugal]], and after 1917 the [[United States]].

World War I also saw the first use of [[poison gas]], large artillery, armored [[tank|tanks]], and [[airplane]]s. It was a "[[total war]]" because the governments involved took control over the economy and factories, giving first priority to the goods needed for war. Wage and price controls were imposed, there was rationing of goods for civilians, and free speech was limited.  The governments put out [[propaganda]] to maximize support for the war and dislike of the enemy.  Many of the techniques of population manipulation and central government control which we see today were first pioneered by European powers during World War I.
