The Seventeenth Amendment (Amendment XVII) to the United States Constitution established the popular election of United States senators by the people of the states. The amendment supersedes Article I, §3, Clauses 1 and 2 of the Constitution, under which senators were elected by state legislatures.
The Sixteenth Amendment (Amendment XVI) to the United States Constitution allows Congress to levy an income tax without apportioning it among the states on the basis of population. It was passed by Congress in 1909 in response to the 1895 Supreme Court case of Pollock v. Farmers' Loan & Trust Co.
