About: 1884–85 United States Senate elections

The 1884–85 United States Senate elections were elections that coincided with the presidential election of 1884. Both Republicans and Democrats lost seats in the United States Senate due to the failure of three state legislatures to finish elections in time. Republicans, nevertheless, retained majority control and the Readjusters joined their caucus. By the beginning of the first session, in December 1885, Republicans had won all three vacant seats, increasing their majority. As these elections were prior to ratification of the seventeenth amendment, Senators were chosen by state legislatures.
