The [[Massachusetts Senate]] is the upper house of the [[Massachusetts General Court]], the [[bicameral]] state legislature of the [[Commonwealth (U.S. state)|Commonwealth]] of [[Massachusetts]]. The Senate comprises 40 elected members from 40 single-member senatorial districts in the state. Descended from the colonial legislature, the current Massachusetts Senate was established in June 1780 upon the adoption of the [[Massachusetts Constitution]]. The [[1st Massachusetts General Court (1780)|first]] General Court met in October 1780 and consisted of one-year elected terms for both houses. This was expanded to two-year terms starting with the [[142nd Massachusetts General Court (1921-1922)|142nd]] General Court in January 1921. The current delegation is the [[191st Massachusetts General Court (2019–2020)|191st]] General Court (2019–2020), consisting of 34 [[Democratic Party (United States)|Democrats]] (D) and 6 [[Republican Party (United States)|Republicans]] (R).
