The New Deal had a profound impact on American politics by reshaping the role of the federal government in economic and social welfare. Introduced during the Great Depression, it established a framework for government intervention in the economy, aiming to provide relief, recovery, and reform. This shift led to the development of significant policies and programs such as Social Security and labor rights, effectively modernizing the American socio-economic landscape. The New Deal also solidified the Democratic Party as a dominant political force, influencing subsequent political ideologies and party platforms.
