How did the war with Mexico begin?

Question

a
a border dispute
b
U.S. invasion of Mexico City
c
the battle at the Alamo
d
Mexico’s invasion of the California Territory

Answer 1

The war with Mexico began primarily due to a border dispute (option a). The conflict was triggered by disagreements over the boundaries of Texas after it was annexed by the United States. Tensions escalated when U.S. troops were sent into the disputed territory, leading to skirmishes and ultimately the declaration of war in 1846.
