The presidents during the Great Depression were Herbert Hoover and Franklin Delano Roosevelt (FDR). Herbert Hoover served as president from 1929 to 1933, when the Great Depression began following the stock market crash in October 1929. His policies were widely seen as ineffective in addressing the economic crisis. Franklin D. Roosevelt succeeded Hoover in 1933 and served until 1945. Roosevelt implemented the New Deal programs aimed at relief, recovery, and reform, which helped mitigate the effects of the Depression and ultimately ended it by 1941 with the economic boost from World War II
