The Mexican-American war has began at April 25, 1846 and ended at February 2, 1848. The reason that how it has started was because the U.S. annexation of Texas and the result of disagreement over where the Mexican-American border should be so it was breaker out in Texas. It has ended by a treaty Guadalupe Hidalgo. The treaty of Guadalupe Hidalgo ended the Mexican-America war. The treaty was signed at the February 2, 1848 and it is the oldest treaty still in force between the United States and Mexico. These are the information of how it started, ended, and how was there a truce but I will tell more information along the way.
