World War I saw the first use of [[poison gas]], large [[artillery]], armored [[tank]]s, 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. | World War I saw the first use of [[poison gas]], large [[artillery]], armored [[tank]]s, and [[airplane]]s.
