Note: The Senate first convened in December 1790. The length of legislative sessions has varied throughout the history of the Senate. For the sake of consistency, Senators are listed in this database as serving in two-year increments, although this may not always have been the case. The Pennsylvania Manual's section on The General Assembly includes a detailed history of session lengths.
