Texas is a U.S. state that borders Mexico, with a border extending about 1,254 miles along the Rio Grande River. Historically significant, Texas was once part of Mexico before joining the U.S. in 1845, contributing to the Mexican-American War. Other states that border Mexico include California, Arizona, and New Mexico, but Texas is the most prominent due to its size and history.
