Document 3: Franklin D. Roosevelt: Franklin Delano Roosevelt (/ ˈroʊzəvəlt /, his own pronunciation, or / ˈroʊzəvɛlt /; January 30, 1882 -- April 12, 1945), commonly known as FDR, was an American statesman and political leader who served as the 32nd President of the United States from 1933 until his death in 1945. A Democrat, he won a record four presidential elections and emerged as a central figure in world events during the mid-20th century. He directed the United States government during most of the Great Depression and World War II. As a dominant leader of his party, he built the New Deal Coalition, realigning American politics into the Fifth Party System and defining American liberalism throughout the middle third of the 20th century. He is often rated by scholars as one of the three greatest U.S. Presidents, along with George Washington and Abraham Lincoln.

However, Universal retained ownership of Oswald cartoons produced for them by Walter Lantz from 1929 to 1943.
Document 5: Great Depression in the United States: The Depression caused major political changes in America. Three years into the depression, President Herbert Hoover, widely blamed for not doing enough to combat the crisis, lost the election of 1932 to Franklin Delano Roosevelt in a landslide. Roosevelt's economic recovery plan, the New Deal, instituted unprecedented programs for relief, recovery and reform, and brought about a major realignment of American politics.
Document 6: Dust Bowl: During President Franklin D. Roosevelt's first 100 days in office in 1933, his administration quickly initiated programs to conserve soil and restore the ecological balance of the nation. Interior Secretary Harold L. Ickes established the Soil Erosion Service in August 1933 under Hugh Hammond Bennett. In 1935, it was transferred and reorganized under the Department of Agriculture and renamed the Soil Conservation Service. It is now known as the Natural Resources Conservation Service (NRCS).
Document 7: Twenty-second Amendment to the United States Constitution: Franklin D. Roosevelt spent the months leading up to the 1940 Democratic National Convention refusing to state whether he would seek a third term. His Vice President, John Nance Garner, along with Postmaster General James Farley, announced their candidacies for the Democratic nomination. When the convention came, Roosevelt sent a message to the convention, saying he would run only if drafted, saying delegates were free to vote for whomever they pleased. The delegates issued 946 votes for Roosevelt, 72 for Farley, and 61 for Garner; they replaced Garner with Henry A. Wallace as the vice presidential nominee, and Farley resigned as postmaster general. In the 1940 general election, while Republican Wendell Willkie received six million more votes than the previous Republican candidate (Alfred Landon) had in 1936, Roosevelt still won decisively, taking 38 of 48 states. His supporters cited impending war as a reason for breaking with precedent, while Willkie had run against the principle of a third term. Roosevelt was the first president elected to a third term, and remains the only one to exceed eight years in office.

Document 15: Universal Pictures: The production arm of the studio still struggled. While there were to be a few hits like The Killers (1946) and The Naked City (1948), Universal-International's new theatrical films often met with disappointing response at the box office. By the late 1940s, Goetz was out, and the studio returned to low-budget films. The inexpensive Francis (1950), the first film of a series about a talking mule and Ma and Pa Kettle (1949), part of a series, became mainstays of the company. Once again, the films of Abbott and Costello, including Abbott and Costello Meet Frankenstein (1948), were among the studio's top-grossing productions. But at this point Rank lost interest and sold his shares to the investor Milton Rackmil, whose Decca Records would take full control of Universal in 1952. Besides Abbott and Costello, the studio retained the Walter Lantz cartoon studio, whose product was released with Universal-International's films.
