Final answer:
The War of 1812 was caused by the British impressment of American sailors and their support of Native Americans, along with the lack of a peaceful solution. This led to the United States declaring war on Britain in 1812.
Step-by-step explanation:
The War of 1812 was primarily caused by unresolved issues between the United States and Great Britain. One major reason for America's entrance into the war was the British practice of impressment, where American sailors were taken and forced to fight on British warships.
Additionally, the British in Canada supported Native Americans in their fight against U.S. expansion in the Great Lakes region. These actions, along with the lack of a peaceful solution, led to the United States declaring war on Britain in June 1812.
In summary, the factors that led to America's entrance into the conflict:
- Impressment
- Trade Restrictions
- Native American Relations
- National Honor and Sovereignty
- War Hawks Influence
- Manifest Destiny
