El Pueblo History Museum in Pueblo, Colorado, connects the modern city to the original El Pueblo trading post from which it took its name. The site traces a borderlands past shaped by trade, shifting empires, war, migration, and conflict: the post was built in 1842, declined after the Mexican–American War and the Treaty of Guadalupe Hidalgo, and was abandoned after an 1854 attack by Ute and Jicarilla Apache forces led by Chief Tierra Blanco. Archaeological work in the late twentieth century rediscovered the long-lost fort, and the museum now combines exhibits, excavation, reconstruction, and community programs to explore Pueblo’s diverse regional history.
