29th United States Congress



The Twenty-ninth 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, 1845 to March 3, 1847, during the first two years of the administration of U.S. President James K. Polk.
