Explanation:

One of the most important points of Franklin D. Roosevelt's 1932 election campaign was the start of a bold new plan of action to rescue the nation from the effects of the Great Depression of 1929, the worst economic disaster of the twentieth century.

Elected by an overwhelming majority of votes, Roosevelt took office in March 1933 and was able to approve in Congress in just one hundred days his groundbreaking economic plan, which he called the New Deal.
