Which President initiated the New Deal during the Great Depression?

The New Deal was a series of programs and reforms designed to address the economic challenges of the Great Depression, which began in 1929. Franklin D. Roosevelt, who became president in 1933, is credited with initiating these sweeping measures to promote recovery, provide relief for the unemployed, and reform the financial system. His approach included enacting legislation that created social safety nets and established agencies that continue to impact American society today, such as the Social Security Administration and the Federal Deposit Insurance Corporation.

The other individuals mentioned did not initiate the New Deal. Theodore Roosevelt, for instance, served prior to the Great Depression and had his own set of progressive reforms, but he was not involved in the New Deal initiatives. Herbert Hoover was president at the onset of the Great Depression and is often associated with the initial government response, but he did not implement the New Deal itself. Lyndon B. Johnson's administration came years later and focused on a separate set of reforms and social programs often referred to as the Great Society. Therefore, Franklin D. Roosevelt stands out as the president who took decisive action through the New Deal in response to the economic crisis.
