A major reason for the end of the Great Depression was an increase in government spending 1. for Social Security 2. for space exploration 3. for environmental protection 4. associated with the war effort

Economists and historians hold the view that the beginning of World War II in 1939 was a major event that ended the Great Depression. This is as a result of the Government's spending on the preparation forward at the very least accelerated the recovery from the depression.

For instance, it is believed that policies such as the rearmament policies helped to stimulate Europe's economy by reducing unemployment between 1937 and 1939 and the start of the war brought an end to the unemployment siege that was prevalent during the Depression

The reduction in the unemployment rate as a result of spending on the war was also witnessed in the United States as historians and economists believed that US' entry into the war n 1941 drastically reduced the rate of unemployment to below 10%.

What exactly was this spending associated with war efforts, the government in preparation for the war started enacting policies that established numerous contracts on arms and equipment with many private contractors and businessmen and these companies needed to employ people and also commit to these contracts to secure their gains and these were very key in ending the Great Depression.
