43RD CONGRESS- SENATE The SENATE of the 43rd Congress included 1 Senator from other than the two Major Parties as elected by his respective State Legislature, as follows:
The SENATE of the 43rd Congress also included 1 vacancy from the State of LOUISIANA in the Class 3 seat (term: 4 March 1873 to 3 March 1879) from that State: William L. McMillen, a Democrat, and Pinckney B.S. Pinchback, a Republican, each claimed to have been elected by the legitimate General Assembly of the State. The Senate took no action on this dispute during the 43rd Congress and this seat remained vacant throughout that Congress. George Boutwell, a Republican, was elected on 12 March 1873 by the General Court of the Commonwealth of MASSACHUSETTS to the Class 2 seat (term ending 3 March 1877) from that State vacated by the resignation of Senator Henry Wilson on 3 March 1873, at the end of the preceding Congress, to become Vice President of the United States, before the convening of the "long" session of the 43rd Congress on 1 December 1873; Senator Boutwell, therefore, is counted among the 54 Republicans elected to the Senate of the 43rd Congress, notwithstanding the existence of a vacancy at the start of that Congress [4 March 1873]. | |||||||||
