The Interwar period (also interbellum) is understood within Western culture to be the period between the end of the First World War and the beginning of the Second World War in Europe, specifically 11 November 1918 to 1 September 1939. It was marked by turmoil in much of the world, as Europe struggled to recover from the devastation of the First World War. In North America the first half of the interwar period is often seen as one of considerable prosperity, but this changed dramatically with the onset of the Great Depression in 1929.
