The Rush–Bagot Treaty was a pivotal agreement between the United States and Great Britain that sought to limit naval power on the Great Lakes and Lake Champlain after the War of 1812. This treaty was negotiated by Richard Rush, U.S. Secretary of State, and Charles Bagot, British Minister to the U.S., and marked a significant step in reducing tensions between the two nations. The treaty allowed for only a limited number of naval vessels on the Great Lakes, thus preventing an arms race on these vital waterways.

While the War of 1812 had solidified American independence, it also left lingering hostilities and unresolved issues. The sinking of ships and the fortification of naval bases on these lakes had been a point of contention. The Rush–Bagot Treaty not only helped to alleviate military tensions but also fostered cooperation between the two nations. The treaty functioned as both a practical measure to maintain peace and a symbolic gesture that demonstrated a commitment to mutual understanding.

In the longer term, the Rush–Bagot Treaty laid the foundation for a stable and peaceful border between the United States and Canada. As a result, the significant demilitarization of the Great Lakes made way for increased trade and economic cooperation. The agreement also set a precedent for further disarmament treaties in the years to come, ultimately contributing to a more secure and amicable relationship in North America. This cooperation would be crucial during periods of future international tension and conflict.
