Mexico was as you will see on the map that
follows.
Texas, and now the
United States, claimed
the border at the Rio

territory as far north
as the Nueces River.

that the U.S. considered it’s border.
Predictably, Taylor’s troops were attached by the
Mexican army.
Polk had what he wanted, a war with Mexico.

Polk’s message to Congress“...after reiterated menaces, Mexico has passed
the boundary of the United States, has invaded
our territory and shed American blood upon
the American soil. She has proclaimed that
hostilities have commenced, and that the two
nations are now at war...I invoke the prompt
action of Congress to recognize the existence
of the war, and to place it at the disposal of the
Executive the means of prosecuting the war
with vigor...”

Slavery
One major problem faced the United States
after the war with Mexico. Would slavery be

a great deal of conflict over this issue.
