Ashburton treaty

Ashburton treaty, 1842. After the War of 1812, relations between Britain and the USA remained difficult, with a number of problems including border disputes in Maine. In 1841 when Peel took office, the situation was bad enough to call for naval deployments in case of war. Peel dispatched Lord Ashburton, who had an American wife, as a special envoy. By the treaty, signed in April 1842, Britain dropped the right of maritime search, the Maine border was adjusted, and the rest of the boundary with Canada agreed as the 49th parallel. The Oregon question remained at issue but one of the last acts of Peel's government in 1846 was to reach a settlement on that as well.

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
