# Maine's 1st congressional district

Maine's 1st congressional district is a congressional district in the U.S. state of Maine. The geographically smaller of the state's two congressional districts, the district covers the southern coastal area of the state. The district consists of all of Cumberland, Knox, Lincoln, Sagadahoc, and York counties, and most of Kennebec County. Located within the district are the cities of Portland, Brunswick, and Saco. The district is currently represented by Democrat Chellie Pingree.

## History

Maine was initially a part of the state of Massachusetts. Massachusetts was allocated 20 districts after the 1810 U.S. census. When Maine became a state in 1820, seven of those districts were credited to it. Since then, all but the 1st and 2nd congressional districts have become obsolete.
