The House is uniquely the only state legislative body in the U.S. to set aside special seats for American Indians,[1] where there are three non-voting Representatives from the Penobscot Nation, the Passamaquoddy Tribe, and the Houlton Band of Maliseets.

In 1922, Dora Pinkham became the first woman elected to the Maine State Legislature, serving first in the House and then in the Senate.

It appears that prior to Maine's statehood, Massachusetts allowed the tribes to send in representatives.

In 2015, the Passamaquoddy and Penobscot pulled their representatives from the legislature in protest of growing tension between the tribes and the state government, including Governor Paul LePage.

Starting in 1881, an amendment to the Maine Constitution took effect to provide for two-year terms, the current length.

The second session is typically short and deals with a limited number of bills per the Maine Constitution, which are budgetary matters, legislation submitted by the Governor, bills held over from the first session, citizen initiatives, and legislation deemed to be an 'emergency'.

[9] The governor of Maine may also call the legislature into a special session for "extraordinary occasions."

[10] As the legislative branch of the Maine state government, the legislature has the power to make laws, subject to a veto by the governor.

Most states give this responsibility to gubernatorial appointments, or an election by the people at large.
