On the grounds of Old Fort Niagara (43°15′48″N 79°03′49″W / 43.263347°N 79.063719°W / 43.263347; -79.063719) stands a monument with reliefs of Rush and Bagot and the words of the treaty. [10] Bagot met informally with Secretary of State James Monroe and eventually reached an agreement with his successor, Acting Minister Richard Rush. The agreement limited military navigation on the Great Lakes to one to two ships per country on each sea. The U.S. Senate ratified the agreement on April 28, 1818. The British government considered that a diplomatic exchange of letters between Rush and Bagot was sufficient to make the agreement effective. ● This meant improved diplomatic relations between the United States and Britain● The agreement ended the costly arms race on the Great Lakes that had begun with the War of 1812● The Rush Bagot Treaty was therefore the first treaty to reduce armaments The importance of the Rush Bagot Agreement: What was the significance of the Rush Bagot Treaty? The Rush Bagot agreement was important because: What is the Rush Bagot agreement? The Rush-Bagot treatise was extremely unusual as it was based on an exchange of notes (letters) between Richard Rush and Sir Charles Bagot.

The terms were proposed to Richard Rush by President Monroe in a letter dated August 2, 1816. The method of reaching an agreement between the American and British governments was the diplomatic means known as the “exchange of notes”. A number of notes were passed between Rush and Bagot and they reached an agreement. In 1818, the U.S. Senate gave its approval to the notes, giving them the authority of a treaty. The simple exchange of notes between the two diplomats thus became the Treaty of Rush-Bagot. Although the treaty caused difficulties during the First World War, its terms were not changed. Similar problems arose before World War II, but Foreign Minister Cordell Hull wanted to preserve the agreement because of its historical importance. In 1939 and 1940, Canada and the United States agreed to interpret the treaty so that weapons could be installed in the Great Lakes, but would no longer be functional until ships left the lakes. In 1942, the United States, now at war and allied with Canada, successfully proposed that the weapons could be fully installed and tested in the lakes by the end of the war. After discussions in the Permanent Joint Defence Council in 1946, Canada also proposed to interpret the agreement to allow the use of ships for training purposes when each country notifies the other. [9] The Rush-Bagot Pact was an agreement between the United States and Great Britain to eliminate their fleets from the Great Lakes, with the exception of small patrol ships.

The Convention of 1818 established the boundary between the Missouri Territory in the United States and British North America (later Canada) at the forty-ninth parallel. Both agreements reflected the easing of diplomatic tensions that had led to the War of 1812 and marked the beginning of Anglo-American cooperation. Although the agreements did not fully discuss border disputes and trade agreements, the Rush Bagot Agreement and the 1818 Convention marked an important turning point in Anglo-American and American-Canadian relations. .
