What were the causes and effects of the war of 1812?

The War of 1812 was primarily caused by British restrictions on American trade, impressment of American sailors into the Royal Navy, and conflicts with Native Americans in the Northwest Territory. The war led to increased nationalism in the United States and fostered a sense of unity and identity. Additionally, it resulted in the decline of the Federalist Party, which opposed the war, and prompted the U.S. to bolster its military and industrial capabilities. Ultimately, the war solidified American independence and ended the threat of British interference in American affairs.
