Mexico was angered when Texas was annexed—and became a state—in 1845. In addition, Mexico
and the United States disagreed about the location of Texas’s (1) BORDERS.
U.S. President (2) POLKsent Slidell to Mexico with an unsuccessful offer to
purchase disputed land in Texas and the Mexican-owned territories of
(3)NEW MEXICO and California. When (4)GENERAL ZACHARY TAYLOR’S troops
blockaded the (5) RIO GRANDE RIVER, Mexico viewed the action as an invasion and
attacked the U.S. soldiers near Matamoros. In response, President Polk successfully urged Congress
to declare war. Polk then ordered General Kearny to capture (6) NEW MEXICO, which
was accomplished without bloodshed. In the meantime, American settlers in
(7) CALIFORNIA led by John C. Fremont overthrew the Mexican government in the
town of Sonoma and established an independent nation that they called the
(8) BEAR FLAG REPUBLIC. General(9) KEARNY arrived and joined forces
with the U.S. Navy to complete the conquest of (10) CALIFORNIA.
The war with Mexico was also going on in the territory of (11) TEXAS and in
Mexico. In September 1846, General (12) TAYLOR’s troops captured the city of
Monterrey. (13) SANTA ANNAdid not honor an agreement made with Polk to end the
war and led troops in a battle at Buena Vista, which they lost. In the meantime, General Scott moved
toward (14) MEXICO CITY, and captured the capital.
The signing of the Treaty of (15) GUADALUPE HILDALGO ended the war. As a result, the United
States gained vast amounts of land. More was added when President (16) PIERCE
authorized the (17) GADSDEN PURCHASE in 1853. These two events, together, set the
present-day borders of the lower 48 states.
