Porvenir may be best known for an incident in 1918 called the Porvenir Massacre, in which the Texas Rangersqv, assisted by United States Army troopers of the Eighth Cavalry and ranchers on a search for outlaws, shot and killed fifteen Mexican men. The village was abandoned for several years after the massacre. In 1918 the population of Porvenir was estimated at 140. A post office was established in 1926. By 1940 Porvenir had a single business and a population of twenty. In 1948 the post office was discontinued, and no further population figures were recorded for the town.
