The 1798–99 United States Senate elections were held on various dates in various states. As these U.S. Senate elections were prior to the ratification of the Seventeenth Amendment in 1913, senators were chosen by state legislatures. Senators were elected over a wide range of time throughout 1798 and 1799, and a seat may have been filled months late or remained vacant due to legislative deadlock.[1] In these elections, terms were up for the senators in Class 2.
They occurred in the middle of President John Adams's administration, and had no net change in political control of the Senate.
