Webster-Ashburton Treaty for kids: Background History
The Webster-Ashburton Treaty was a result of disputes over the boundary line between U.S. state of Maine and
and the British Canadian province of New Brunswick. Previous treaties had been unable to reach agreements as to the border line because the disputed area had not been fully explored or mapped. A serious international incident called the Aroostook War had erupted in 1839 due to the dispute. There was no actual fighting (although it came very close) due to the intervention of President Martin Van Buren who sent General Winfield Scott to Aroostook to diffuse the situation. General Winfield Scott negotiated a truce and both sides agreed to joint occupancy of the disputed area until a satisfactory settlement could be reached. The primary purpose of the Webster-Ashburton Treaty was to resolve this issue.

Webster-Ashburton Treaty for kids
The signing of the Webster-Ashburton Treaty between the United States and Great Britain was one of the
most important events during President John Tyler's administration. Ever since the Treaty of Peace of 1783, there had been a dispute over the northeastern boundary of Maine. Maine became a state in 1820 and began granting land to settlers in the Aroostook Valley, ignoring British Canadian claims. If the boundary had been run according to an interpretation of the Treaty of Peace, the people of Upper Canada would have found it almost impossible to reach New Brunswick or Nova Scotia during the winter. During the winter months the St. Lawrence River is frozen over, and the northern boundary of Maine ran so close to the St. Lawrence that it was difficult to build a road which would be wholly in British territory. It had therefore been in the interests of British to avoid settling the issue. The Aroostook War had brought the dispute to a head - it was essential for the dispute to be resolved.
