The Salt War grew out of political conflicts in El Paso County and disputes over control of the salt lakes east of El Paso, which for centuries had been a free source of salt for local residents. In 1877 Charles Howard, a former county judge who claimed ownership of the lakes, shot political adversary Luis Cardis over the issue of the salt beds. While under the protection of state troops in San Elizario, Howard and several troopers were killed by a riotous mob. Federal and state investigations of the Salt War led to the reestablishment of Fort Bliss in 1878.
