The 37th United States Congress was a meeting of the legislative branch of the United States federal government, consisting of the United States Senate and the United States House of Representatives. It met in Washington, D.C., from March 4, 1861, to March 4, 1863, during the first two years of Abraham Lincoln's presidency.^[1] The apportionment of seats in the House of Representatives was based on the 1850 United States census.

For the first time since the party's establishment, the Republicans won the majority of both chambers, and thus full control of Congress. And with Abraham Lincoln becoming the first Republican President after being sworn in on March 4, 1861, the Republicans had their first ever overall federal government trifecta.
