Coahuila (state in northern Mexico)

Geography and climate

Much of Coahuila lies within the Chihuahuan Desert and along the eastern slope of the Sierra Madre Oriental. The terrain includes arid basins, rocky hills and higher, cooler mountains. Climate ranges from desert and semi‑arid in lowland areas to temperate in upland zones, with marked temperature swings between day and night.

Major cities and regions

• Saltillo — the political and cultural capital.
• Torreón — part of the Laguna metropolitan region and a major commercial center.
• Monclova — known for steelmaking and heavy industry.
• Piedras Negras and Ciudad Acuña — important border cities on the Río Bravo (Rio Grande).

History and culture

The region was home to indigenous groups before Spanish colonization. During the colonial and republican eras it developed cattle ranching, mining and small agricultural settlements. Coahuila’s official name honors General Ignacio Zaragoza. The state has colonial architecture, traditional crafts such as Saltillo’s sarape weaving, and historic vineyards—Parras de la Fuente is often cited among the oldest wine-producing areas in the Americas.

Economy and resources

Coahuila’s economy combines mining, heavy industry (notably steel production), manufacturing maquiladoras near the border, and agriculture including cattle and cotton. The La Laguna area around Torreón is an important industrial and agricultural basin shared with neighboring Durango. Mining and energy extraction have also shaped regional development.
