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