War of a Thousand Deserts: Indian Raids and the U.S.-Mexican War

In the early 1830s, after decades of relative peace, northern Mexicans and the Indians whom they called "the barbarians" descended into a terrifying cycle of violence. For the next fifteen years, owing in part to changes unleashed by American expansion, Indian warriors launched devastating attacks across ten Mexican states. Raids and counter-raids claimed thousands of lives, ruined much of northern Mexico's economy, depopulated its countryside, and left man-made "deserts" in place of thriving settlements. Just as important, this vast interethnic war informed and emboldened U.S. arguments in favor of seizing Mexican territory while leaving northern Mexicans too divided, exhausted, and distracted to resist the American invasion and subsequent occupation.
