Maine became a state in 1820 but its northern border was the subject of a dispute between the US and Canada. The King of the Netherlands was called on to settle this and drew up his own border. A treaty established this in 1842. The lines of the various borders, 1783, 1842 and that of the King of the Netherlands are clearly marked in the north. The final border of 1842 gives up more land to Canada. Box at top right detailing the populations
