Final answer:
The primary actions that contributed to the start of the War of 1812 were the British practice of impressment and their support of Native American resistance.
Step-by-step explanation:
The War of 1812 was fought between the United States and Great Britain from 1812 to 1815. Causes included maritime issues, the impressment of American sailors, and territorial disputes. The conflict ended with the Treaty of Ghent, restoring pre-war borders and fostering a sense of national identity in the U.S.
The War of 1812 was primarily caused by two main actions: the British practice of impressment and their support of Native American resistance. Impressment involved the British capturing American sailors at sea and forcing them to serve on British warships. This issue was not resolved by the Jay's Treaty in 1794. Additionally, the British in Canada supported Native Americans in their fight against U.S. expansion in the Great Lakes region. These actions, along with other factors, led to the start of the War of 1812.
