What Started The Mexican War?

In 1845 Texas became a state. After this Mexico broke off all diplomatic relations with the the United States because…– Mexico still considered Texas to be a

Mexican territory. Shortly after a dispute arose between

Texas and Mexico about where the boundary between them was.

Both sides claimed they owned the land between the 2 rivers.

AMERICANS WANTED WAR!!!!

-Many citizens thought the U.S. should force Mexico to pay $3 million for property taken or destroyed.

-Others believed it was the “manifest destiny” of the U. S. to move into the new territory out West.

Steps Towards War

Just north of the river a small number of U. S. cavalrymen were defeated by a larger Mexican force.
