Daniel Webster, Secretary of State, and Privy Counsellor Alexander Baring, Baron of Ashburton, of the United Kingdom, sign the Webster–Ashburton Treaty, peacefully resolving several border disputes between the United States and British North American colonies, particularly the location of the boundary between Maine against Quebec and New Brunswick.  The treaty also clarified the details of the “Northwest Angle” (the border between Lake Superior and the Lake of the Woods) originally ill-defined in the 1783 Treaty of Paris; reaffirmed the location of the border (at the 49th parallel) in the westward frontier between the Lake of the Woods up to the Rocky Mountains, originally defined in the Treaty of 1818; called for a final end to the slave trade on the high seas, to be enforced by both signatories; and agreed on terms for shared use of the Great Lakes.

       NOTE: In an attempt to make the treaty more palatible with the Union’s Electorate, Webster published a map, said to have been drawn by Benjamin Franklin, showing British ownership of the areas of Quebec and New Brunswick claimed by  Mainers.
