Step-by-step explanation:
In the aftermath of the War of 1812, both Great Britain and the United States took measures to improve their relationship and avoid further conflict. The British reached out to the Americans to address unresolved issues, resulting in several agreements that brought long-term peace between the two nations. The Rush-Bagot Agreement of 1817 demilitarized the Great Lakes region and the Congress of 1818 set boundaries and provided for American fishing rights. These agreements, along with the Anglo-American rapprochement, improved foreign trade and economic health for both countries.
