Maine's at-large congressional district

When Maine became a state on March 15, 1820, it was apportioned one seat in the United States House of Representatives for the remainder of the 16th United States Congress until March 3, 1821. Starting with the 17th Congress, six more seats were reapportioned (moved, essentially) from Massachusetts and districts were established, thereby eliminating the at-large seat.

During the 48th Congress (1883–1885), Maine elected its four members of the United States House of Representatives at-large statewide, on a general ticket.
