The primary architect of the New Deal in the U.S. during the Great Depression was President Franklin D. Roosevelt. Elected in 1932, Roosevelt responded to the economic crisis with a series of programs aimed at providing relief, recovery, and reform. The New Deal included initiatives like Social Security, banking reforms, and various public works projects, which sought to stimulate the economy and provide jobs. His administration redefined the role of government in American life, emphasizing federal responsibility for citizens' welfare. The New Deal's legacy continues to influence U.S. social policies and debates related to government intervention in the economy.
