War with Mexico
An armed conflict between the United States and Mexico between 1846 and 1848.
The conflict occurred due to a dispute over the border between Texas and Mexico.- The U.S. claimed the border was the Rio Grande.- Mexico claimed the border was the Nueces River.
This created a disputed zone claimed by both countries.
War with Mexico
President James Polk was very interested in gaining the Mexican land to the west. He offered Mexico $30 million, but was rejected. He needed a war, but didn’t have support from the public or Congress. What did he do?
Polk sent General Zachary Taylor into the disputed territory.- The U.S. believed they were defending their land.- Mexico believed they were invaded.

In response, Mexican General (and part-time president) Santa Anna sent troops to defend their land. He crossed the Rio Grande and attacked an American force, killing 11 U.S. soldiers.
President Polk informed Congress that the U.S. had been “invaded” and “attacked” by Mexico. The incident was called the Thornton Affair.
- Congress declared war 3 weeks later (May 13, 1846)
