Several amendments to the United States Constitution were passed as a result of the efforts of progressive reformers. Federal income taxes were enacted in the 16th Amendment, the Seventeenth Amendment provided for the direct election of Senators, the Eighteenth Amendment restricted the sale of alcohol, and the Nineteenth Amendment guaranteed women's ability to vote in the United States.
They accomplished many notable things during this time, but Progressive reformers pushed discriminatory regulations and held anti-tolerant views. For example, the Wilson administration pursued a racial agenda that culminated in the segregation of the federal government, despite its embrace of modernity and progress. During Wilson's administration (1913-1921), the Ku Klux Klan saw a resurgence and the post-Reconstruction accomplishments of African Americans were violently resisted.
