The 19th 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, 1825, to March 4, 1827, during the first two years of John Quincy Adams's presidency. The apportionment of seats in the House of Representatives was based on the 1820 United States census. The Senate had a majority of Jackson Men, while the House had an Anti-Jackson (pro-Adams) majority.
The 1826–27 United States House of Representatives elections were held on various dates in various states between July 3, 1826, and August 30, 1827. Each state set its own date for its elections to the House of Representatives before the first session of the 20th United States Congress convened on December 3, 1827. They occurred during John Quincy Adams's presidency. Elections were held for all 213 seats, representing 24 states.
The 1827 United States Senate election in New York was held on February 6, 1827, by the New York State Legislature to elect a U.S. Senator to represent the State of New York in the United States Senate.
The 1826–27 United States Senate elections were held on various dates in various states. As these U.S. Senate elections were prior to the ratification of the Seventeenth Amendment in 1913, senators were chosen by state legislatures. Senators were elected over a wide range of time throughout 1826 and 1827, and a seat may have been filled months late or remained vacant due to legislative deadlock. In these elections, terms were up for the senators in Class 1.
The 1827 New Hampshire gubernatorial election was held on March 13, 1827.
