1790 and 1791 United States House of Representatives elections

The 1790 and 1791 United States House of Representatives elections, took place in the middle of President George Washington's first term. While formal political parties still did not exist, coalitions of pro-Washington (pro-Administration) representatives and anti-Administration representatives each gained two seats as a result of the addition of new states to the union.

Speaker Frederick Muhlenberg, who had led the Pro-Administrationists in 1789, switched loyalties to the Anti-Administrationists during the tenure of the 1st Congress. He failed to win election to the Speakership as their leader as a result of these elections, and was succeeded by Jonathan Trumbull Jr., who became the 2nd Speaker of the House.
