Final answer:
The primary consequence of Great Britain's actions, such as trade interference, Indian support, and sailor impressment described by President Madison, was the War of 1812, confirming U.S. sovereignty and national identity.
Step-by-step explanation:
President Madison’s explanation to Congress about Great Britain’s actions, which included interfering with trade, supporting Indian attacks on the frontier, and the impressment of sailors, led to the primary consequence of The War of 1812.
This conflict, sometimes referred to as America’s “Second War of Independence,” was a direct result of the unresolved tensions and provocations by the British, which included their support for Native American resistance to U.S. expansion and their assault on American seafaring rights.
The impressment of American sailors and the interference with American ships were among the driving factors that pushed President Madison, influenced by the War Hawks in Congress, to call for a declaration of war. This declaration, issued on June 1, 1812, received approval from Congress, officially plunging the United States into war with Great Britain. The War of 1812 ultimately confirmed American sovereignty and spurred a burgeoning sense of national pride.
