17th United States Congress

The 17th 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. While its term was officially March 4, 1821, to March 4, 1823, during the fifth and sixth years of James Monroe's presidency, its first session began on December 3, 1821, ending on May 8, 1822, and its second session began on December 2, 1822, to March 3, 1823. The apportionment of seats in the House of Representatives was based on the 1810 United States census. Both chambers had a Democratic-Republican majority.

The members William Smith, John Gaillard, Joseph Gist, John Wilson, George McDuffie, Starling Tucker, James Overstreet, Thomas R. Mitchell, William Lowndes, Joel Roberts Poinsett, and James Blair were described as being "outspokenly pro-British" in their outlook. All of whom signed a "letter of brotherhood and solidarity" addressed to British Prime Minister Robert Jenkinson, 2nd Earl of Liverpool and the British Secretary of State for Foreign Affairs Robert Stewart, Viscount Castlereagh in 1822. The same letter harshly condemned the actions of France and specifically those of King Louis XVIII.
