Membership highlights by chamber
This list is arranged by chamber, then by state. Senators are listed in order of seniority, and Representatives are listed by district.
Senate
Senators were elected by the state legislatures every two years, with one-third beginning new six year terms with each Congress. Preceding the names in the list below are Senate class numbers, which indicate the cycle of their election. In this Congress, Class 1 meant their term ended with this Congress, requiring reelection in 1862; Class 2 meant their term began in the last Congress, requiring reelection in 1864; and Class 3 meant their term began in this Congress, requiring reelection in 1866.
House of Representatives
The names of members of the House of Representatives elected statewide "at-large," are preceded by an "A/L," and the names of those elected from districts, are preceded by their district numbers. Many of the congressional district numbers are linked to articles describing the district itself. Since the boundaries of the districts have changed often and substantially, the linked article may only describe the district as it exists today, and not as it was at the time of this Congress.
