What was the main cause of the War of 1812?

The War of 1812 was primarily driven by trade restrictions imposed by Britain and conflicts arising from American expansionism. During this time, Britain had enacted a series of economic sanctions and trade barriers that hurt American merchants and disrupted trade. The British were trying to restrict American trade with France, which was at war with Britain. These trade restrictions not only limited economic opportunities for the United States but also incited feelings of anger and resentment among Americans.

Additionally, the United States was eager to expand its territory and influence, particularly in regions such as Canada. Many Americans believed that acquiring new territory would bolster the young nation and provide room for its growing population. This desire for expansion often clashed with British interests, particularly in North America, where Britain still had strongholds.

Together, these economic tensions and aspirations for territorial expansion were significant factors leading to the outbreak of the War of 1812, making option B the main cause of the conflict.
