In Mexico, charro is a term referring to a traitional horseman or cowboy of Mexico, originating in the State of Jalisco. In the rest of Mexico, including the part that was annexed by the United States in 1848, the equivalent term was "vaquero". In Spain, a charro is a native of the province of Salamanca, especially in the area of Alba de Tormes, Vitigudino, Ciudad Rodrigo and Ledesma. It is likely that the Mexican charro tradition derived from Spanish horsemen who came from Salamanca and settled in Jalisco.
