The New Deal policies, implemented by President Franklin D. Roosevelt in response to the Great Depression, aimed to revive the U.S. economy and provide relief to those affected by widespread unemployment and poverty. These policies included job creation programs, social security initiatives, and infrastructural investments, which sought to stimulate economic growth and restore public confidence. The New Deal effectively expanded the role of the federal government in economic affairs and initiated welfare programs that still exist today. While there is debate over the extent of their effectiveness, many historians agree that they were crucial in alleviating the worst effects of the Depression.
