The key issue during the War of 1812 was maritime rights and trade restrictions imposed by the British. The United States sought to protect its neutral shipping rights amidst ongoing conflict between Britain and France. British interference included the impressment of American sailors into the Royal Navy and the blockade of U.S. trade with France. These actions led to rising tensions and anger among American citizens, contributing to calls for war. The War of 1812, often dubbed the "Second War of Independence," tested the young nation’s sovereignty and ability to defend its interests, ultimately influencing national identity and unity.
