What was the main cause of the War of 1812?

The main cause of the War of 1812 was British interference with American trade and the impressment of American sailors. During this period, the British Empire was involved in ongoing conflicts with France and sought to control trade and maritime activities that could aid their enemy. As a result, British naval forces often stopped American ships, seized cargo, and forced American sailors into service for the British Navy, a practice known as impressment. This disrespect for American sovereignty infuriated many Americans and was viewed as a violation of their rights.

This interference was compounded by other underlying tensions, including economic competition and political grievances, but the direct actions taken by British forces against American shipping and maritime rights were critical in galvanizing public support for war. While other factors, such as land disputes and expansionist sentiments, played roles in the broader context of American motivations, it was the British actions against American trade and sailors that ultimately triggered the war.
