What were the major catalysts for the War of 1812?

The War of 1812 was primarily driven by increasing tensions between the United States and Great Britain. Several factors contributed to this rising conflict, with the most significant being the British interference with American shipping and trade, their impressment of American sailors into the British navy, and their support of Native American resistance against American expansion into the Northwest Territory.

Additionally, the aftermath of the Louisiana Purchase fostered a sense of national unity and ambition within the United States. As the country expanded westward, conflicts over land and resources became more pronounced, further aggravating relations with Britain, which still held territory in the region and continued to support Native American allies. Hence, the combination of increasing tensions with Britain and territorial expansion after the Louisiana Purchase were critical catalysts leading to the outbreak of the War of 1812.
