The Treaty of Guadalupe Hidalgo which ended the Mexican War (1846-48) designated the main channel of the Rio Grande as the Mexico-U.S. boundary. Disputes arising from frequent changes in the river's course led to the Treaty of 1884 which recognized only those river diversions resulting from natural occurences. The International Boundary Commission was established in 1889 to administer the Treaty of 1884.
