the municipality was named in honor of Dr. Primo Feliciano Marin de Porras, Bishop of Linares.

These indigenous groups were hunters and gatherers, who probably already knew the practice of sowing corn during the planting season.

After the harvest they remained living in the region, as is evidenced by the arrowheads, axes and scraper that have been found around the Loma Larga and at sites near rivers.

Captain Jose Martínez Flores, a native of Saltillo founded the Hacienda San Antonio de los Martinez in 1684.

This led to Joaquin Martinez, his relatives and neighbors to request from the political and ecclesiastical authorities to elevate the hacienda to the status of town (villa).
