Encarnación de Díaz is a town and municipality situated in the far northeast of the state of Jalisco in north-central Mexico. The location sits within a natural pass that serves as a connection between the Los Altos region of Jalisco and points to the north. Historically, this area served as a major thoroughfare for north-south travel from pre-Hispanic times until the 20th century.
The town originated in the 17th century as a way station along a road built through the pass, eventually becoming a formal town in 1760. It functioned as a municipality starting in the late 19th century, though this status was not officially confirmed until the early 20th century. The local economy was traditionally supported by transport and numerous prosperous haciendas until travel patterns shifted and the Mexican Revolution caused a decline in the early 1900s.
The town is notable for its historical significance during the Cristero War of the 1920s, where it served as a center of rebellion. Consequently, it houses Mexico's only museum exclusively dedicated to this conflict. Additionally, the municipality contains a museum featuring various naturally occurring mummies discovered in the local cemetery.
