Texas

Mexico encouraged Americans to settle in Coahuila, the Mexican region of Texas, but tensions developed and the American settlers refused Mexico's offer. Through devastating losses at the Alamo and Goliad, the Americans were able to defeat Mexican force at the Battle of San Jacinto on April 21, 1836. Texas was voted in favor of joining the U.S by the citizens of Texas five months later. However, Texas didn't officially become a state until December of 1845
