The Mexican-American War was the United States' first foreign war, was it too early in American history to make the comparison so commonly seen today? Did opponents to the war use the comparison to liken Polk's actions to tyranny commonly associated with Caesar?
The United States had waged war on many foreign nations before their first conflict with Mexico. Some major wars were the Cherokee-American War, Northwestern Indian War, the Creek War, the Black Hawk War, and the Seminole Wars. And those are just the ones east of the Mississipi.
