Alabama was admitted to the Union on December 14, 1819. The state elects U.S. senators to class 2 and class 3. Its United States Senate seats were declared vacant from March 1861 to July 1868 due to its secession from the Union during the American Civil War. Richard Shelby is Alabama's longest serving senator (served 1987–2023). Alabama's current U.S. senators are Republicans Tommy Tuberville (since 2021) and Katie Britt (since 2023).
