Prior to the arrival of the Spanish, the Río Grande area was inhabited by Chichimeca peoples such as the Guachichil and Irritila. Oral history holds that a Spanish settlement was founded at Río Grande on 18 August 1562. The town was recognized by the Royal Audiencia of Guadalajara on March 5, 1689 under the name Santa Elena de Río Grande.[8]
Río Grande was first incorporated as an ayuntamiento in the partido of Nieves in Zacatecas on 29 October 1833. It became a free municipality on 19 August 1916.[10]
The municipal government comprises a president, a councillor (Spanish: síndico), and fourteen trustees (regidores), eight elected by relative majority and six by proportional representation.[11] The current president of the municipality is Julio César Ramírez López.[2]
In the 2010 Mexican Census, the municipality of Río Grande recorded a population of 62,693 inhabitants living in 15,628 households.[12] It recorded a population of 63,880 inhabitants in the 2015 Intercensal Survey.[5]
