. They named it Nueva Villa de Herrera, but it later became Villa de Piedras Negras. In Otto Schober's "Breve historia de Piedras Negras," the local historian points out that the 34 men were repatriates (Mexican Americans) who arrived on June 15, 1850, in what was then called "Colonia Militar de Guerrero en Piedras Negras." In 1855, the town was looted by a small force of 130 Texans that had been organized by Texas slaveholders for a punitive expedition against a nearby border settlement the Texans claimed contained fugitive

and Native Americans. The force was led by a captain of the Texas Rangers. As it happened, the incursion was opposed and "repelled by a superior force of Negroes, Native Americans, and Mexicans who were waiting in ambush" inside Mexico. But the Ranger-led expedition then looted Piedras Negras while returning to Texas. Following the discovery of huge deposits of coal in the region, in 1881 a railroad track was begun that was completed in 1883. The regional economy flourished and on December 1, 1888, it was granted city status; this time with the name of Ciudad Porfirio Díaz. After the fall of Diaz in 1911, the city reverted to being Piedras Negras, Coahuila. On April 26, 2004, flooding killed 31 people with up to 60 reported missing. On April 24, 2007, an F4 tornado struck the city, killing three people there and seven in Eagle Pass, Texas. From June 14–15, 2013 over 10,000 homes were damaged by flooding and one person was killed. On the night of June 8, 2018, former Piedras Negras mayor was shot in the back of the head by an unknown man while Purón was taking a selfie with an admirer. Purón died on the spot, becoming the 112th candidate or politician to be killed since Mexico's electoral campaign began in September 2017. Purón was supposed to run in the 2018 Mexican election on July 1 as a congressional candidate of the
