Early America
(1775-1860)

In early American history, the United States evolved from a new nation fighting for independence to one whose “manifest destiny” was to settle, conquer and control North America.

The War of 1812 was a conflict fought between the United States, the United Kingdom, and their respective allies from June 18, 1812, to February 18, 1815.

On May 13, 1846, after a request from United States President James K. Polk, Congress declared war on Mexico.
