The 83rd United States Congress was a meeting of the legislative branch of the federal government of the United States in Washington, D.C. from January 3, 1953, until January 3, 1955, during the last two weeks of the Truman administration, with the remainder spanning the first two years of Dwight Eisenhower's presidency. It was composed of the Senate and the House of Representatives. The apportionment of seats in the House was based on the 1950 U.S. census. The Republicans gained the majority in both chambers, winning back full control of Congress for the first time since the 80th Congress in 1947, and with Dwight Eisenhower being sworn in as president on January 20, 1953, this gave the Republicans an overall federal government trifecta for the first time since the 71st Congress in 1929, and the last time until they briefly did so during the 107th Congress in 2001.

Party summary

Until the last week of the first session of Congress, Republicans had a 48-47-1 tied-plurality in the Senate which Republican Vice President Richard Nixon broke in the GOP’s favor. At the start of the second session, to account for whenever the Senate became tied 47-47-1 or when the Democrats held the plurality the Republican-turned-Independent, Wayne Morse, caucused with the GOP which gave them a tie-breaking majority, allowing continuity in GOP control of the Senate and the overall trifecta of government. Thus William Knowland remained Senate Majority Leader, Lyndon B. Johnson remained Senate Minority Leader, and the GOP remained continuously in control of the Senate committees. Wayne Morse would begin caucusing with Democrats at the start of the next Congress in 1955 to give them Senate control.
