Ratified on April 8, 1913, the Seventeenth Amendment (Amendment XVII) to the United States Constitution changed the method by which United States Senators were elected. For the first 125 years Article 1, section 3 of the Constitution required US Senators to be elected by the state legislatures. A number of problems in the United States Senate created the need to change how Senators were elected from indirect to direct elections by the people of the United States.
