Which administration was influenced by the ideology of Progressivism?

The Roosevelt administration was significantly influenced by the ideology of Progressivism, particularly during the New Deal era in the 1930s. Progressivism is characterized by a commitment to social reform, government intervention to address social issues, and an emphasis on scientific approaches to governance. Under Franklin D. Roosevelt, the administration adopted policies aimed at alleviating the hardships of the Great Depression, promoting social welfare, and regulating the economy.

Key initiatives of the New Deal, such as Social Security, labor rights laws, and various public works programs, reflect progressive ideals that sought to improve living conditions and empower the middle and lower classes. This federal government intervention marked a shift toward more active government involvement in economic and social issues, which is a core tenet of Progressivism.

In contrast, the other administrations mentioned do not align as closely with Progressive ideology. For instance, the Reagan administration is often associated with deregulation and reducing the role of government in the economy, while Nixon's policies included some progressive elements but were primarily focused on a broader range of issues, including foreign policy and environmental reforms. The creation of a Bill of Rights predates all these administrations and is more associated with the founding principles of the United States rather than the progressive era's ideas
