Which significant war began due to conflicts in trade and naval rights between the U.S. and Britain?

The War of 1812 began primarily as a result of escalating tensions between the United States and Britain, particularly concerning trade and naval rights. In the years leading up to the war, Britain imposed restrictions on U.S. trade as part of its ongoing conflict with France. This included impressment of American sailors into the British Navy and blockade measures that severely impacted American merchants.

Additionally, American expansionist desires and conflicts with Native American tribes, many of whom were supported by the British, further fueled the desire for war. The culmination of these trade disputes and the infringement on U.S. sovereignty led Congress to declare war against Britain in June 1812. Thus, the War of 1812 is recognized as a direct consequence of these specific conflicts regarding trade and maritime authority, making it the correct answer.

The other wars mentioned are characterized by different causes. The Revolutionary War was fought for American independence from British rule, the War of 1814 is essentially another reference to the War of 1812 with a focus on specific events within it, and the Civil War was primarily about states' rights and slavery rather than trade.
