Maine Statehood
Maine entered the Union through separation from Massachusetts, and its admission became tied directly to the sectional settlement of the Missouri Compromise era.
How This State Entered The Union
Statehood is where constitutional structure meets regional history: the point where a place entered the Union as an equal state.
Admission To The Union
Maine became the twenty-third state on March 15, 1820, after separating from Massachusetts.
Path To Statehood
Its route was unusual: a district became its own state, and admission was linked politically to the Missouri Compromise as part of the balancing of free and slave states.
Why It Matters
Maine matters because it shows how statehood could be both local and national at once. A regional separation became part of a much larger sectional compromise.
