Final answer:
The War of 1812 affected America's policies in the nineteenth century by expanding its territory through deals with Native American tribes and forcibly removing them, as well as investing in coastal fortifications.
Step-by-step explanation:
The War of 1812 had several effects on America's policies in the nineteenth century.
- The American government began to make deals with Native American tribes in order to expand its territory. Treaties such as the Treaty of Fort Wayne and the Treaty of Ghent resulted in the ceding of Native American lands to the United States.
- The American government began violently removing Native Americans from their land in order to expand its territory. The Indian Removal Act of 1830, pushed through by President Andrew Jackson, forcibly relocated Native American tribes such as the Cherokee on the Trail of Tears.
- The American government began to invest heavily in coastal fortifications. Following the War of 1812, there was an increased focus on building coastal defenses, such as forts and batteries, to protect against future attacks.
Therefore, the War of 1812 influenced American policies by both expanding territory through deals with Native American tribes and forcibly removing them, as well as investing in coastal fortifications.
