Cause and effect of Mexican war?

Answer 1

Mexico, angered over the annexation of Texas, attacked Texas settlers in what was by now a US State. As a result, Polk was able to persuade Congress to declare war. After a decisive victory, the United States gained 500,000 square miles of territory including Pacific regions that are now modern day San Diego and San Francisco.

Answer 2

he two-year war (1846-48) was fought over the United States' annexation of Texas. The events that led up to the conflict began in 1837 when President Andrew Jackson (1767-1845) recognized Texas as independent (this was just after Texas had won its war with Mexico). Republic of Texas president Sam Houston (1793-1863) felt that protection against a Mexican invasion may be necessary, so he eyed annexation to the United States. In the meantime, Mexican president Antonio Lopez de Santa Anna (1794-1876) warned that such an action on the part of the United States would be "equivalent to a declaration of war against the Mexican Republic." In June 1844 the U.S. Senate rejected a proposed annexation treaty. But later that year Democratic Party nominee James K. Polk (1795-1849), an ardent expansionist, was elected president. Because the annexation of Texas had figured prominently in his campaign platform, outgoing President John Tyler (1790-1862) viewed Polk's victory as a public mandate for annexation, and he recommended that Congress pass a joint resolution to invite Texas into the union. Congress did so in February, and President Tyler signed the resolution on March 1, 1845, three days before leaving office.
