The Thirty-Ninth Congress of the United States convened from March 4, 1865, to March 3, 1867, during the final years of the American Civil War. It was notable for its efforts to address the issues of reconstruction and civil rights following the war. The Congress was composed of the House of Representatives and the Senate, with significant debates on the future of the Southern states. This Congress is particularly remembered for the passage of the Thirteenth Amendment, which abolished slavery, and the early discussions that led to the Fourteenth Amendment, granting citizenship to former slaves. The political landscape was dominated by the tensions between Republicans and Democrats, shaping the nation’s post-war policies.
