   Founding of Saltillo

   Founding of the Santa María de las Parras mission and Casa Madero

   1598

   Jesuit missionaries and Spanish settlers establish the Santa María de las Parras mission around natural springs; the adjoining Hacienda San Lorenzo, home to Casa Madero, begins producing wine that same era, making it the oldest continuously operating winery in the Americas.

3. 3

   Coahuila y Texas established as a colonial province

   1687

   The Spanish crown organizes the northern frontier territory of Coahuila (later joined administratively with Texas) as a province distinct from Nueva Vizcaya, formalizing Spanish settlement patterns that shaped the region's mission towns and haciendas.

   Royalist forces ambush and capture Miguel Hidalgo, Ignacio Allende and other independence leaders at Acatita de Baján in Coahuila as they fled north; the leaders are subsequently tried and several are executed, marking a major setback for the early independence movement.

7. 7

   Coal and steel industry take root

   1880s-1920s

   Coal mining expands around Múzquiz and the Sabinas Basin, laying the groundwork for Monclova's steel industry; these resources later attract Altos Hornos de México (AHMSA), founded in 1942, which builds Monclova into Mexico's steel capital.

8. 8

   Kickapoo settlement at El Nacimiento

   1850

   Kickapoo, Mascogo and Seminole groups cross the Rio Bravo and settle in Coahuila near Múzquiz after Mexico grants them land in exchange for defending the northern frontier from Comanche and Apache raids; their descendants maintain El Nacimiento de los Kikapú as a sacred, closed community site to this day.

   Coahuila as a cradle of the Mexican Revolution

   1910-1920
