in what year did the US economic recovery begin after World War 1

Was an economic recession that hit much of the world in the aftermath of World War I. In many nations, especially in North America, this growth continued during World War I as nations mobilized their economies to fight the war in Europe. After the war ended, the global economy began to decline. In the United States, 1918-1919 saw a modest economic retreat, but the next year saw a mild recovery. A more severe recession hit the United States in 1920 and 1921, when the global economy fell very sharply.
