What was a key consequence of the War of 1812?

The War of 1812 is often viewed as a second war for independence for the United States. This perspective arises from the war's central issues, which included the ongoing British interference with American shipping and the impressment of American sailors into the British navy. Through this conflict, the United States sought to assert its sovereignty and confirm its status as an independent nation, much as it had done during the American Revolutionary War.

A significant consequence of the War of 1812 was the heightened sense of nationalism that emerged among Americans. The successful defense against British invasions, particularly at places like Fort McHenry, saw the creation of the "Star-Spangled Banner," which became a symbol of American pride. Furthermore, the war solidified the idea of the U.S. as a distinct and independent entity on the global stage, contributing to a growing national identity and promoting the notion of Manifest Destiny in subsequent years.

The other choices do not capture this key consequence accurately. Increased federal debt occurred during the war but is not a distinguishing feature that reflects the broader implications of national identity and independence. While a national currency did develop but would not be established until later, it was not a direct consequence of the war itself. Immediate economic recovery was not a result either;
