  5. 5. u.s. annexation• When James K. Polk, an ardent expansionist, was elected to the presidency in 1844, Congress took that as a message and approved annexation in February, 1845, even before Polk took office, and Texas became a slave state.

  14. 14. results• Five years later, the United States bought 30,000 square miles more along the southern border of Arizona and New Mexico for another $10 million (Gadsden Purchase) so that the nation could build a southern transcontinental railroad.
  15. 15. results• The boundaries of the continental U.S. were now fixed, although the disagreements and misunderstandings between the U.S. and Mexico were going to be the cause of problems between the two nations for many years.
