Chamizal

The Chamizal dispute was an international land and boundary conflict over contested land along the Mexico–United States border between El Paso, Texas, and Ciudad Juárez, Chihuahua. The conflict was caused by multiple meandering, southward shifts in the Rio Grande, which delineates the U.S.-Mexico boundary in this region. When the International Boundary Commission (IBC) first began investigating the dispute in 1895, it discovered that an 1852 survey of the international boundary/Río Grande through El Paso and Cd. Juárez was significantly different from the river's 1895 course.
