Charro is a term referring to a traditional horseman from Mexico, originating in the central-western regions primarily in the states of Jalisco, Michoacan, Zacatecas, Durango, Chihuahua, Aguascalientes, and Guanajuato. The Spanish terms vaquero and ranchero (cowboy and rancher) are similar to the charro but different in culture, etiquette, mannerism, clothing, tradition and social status.
Charreada (a form of rodeo riding practiced by Charro horsemen) has become the official sport of Mexico and maintains traditional rules and regulations in effect from colonial times up to the Mexican Revolution.
The word 'Charro' is first documented in Spain in the 17th century (1627) as a synonym of "person who stops" (basto), "Person who speaks roughly" (tosco), "person of the land" (aldeano), "person with bad taste", and attributes its origins to the Basque language from the word txar which means "bad", "weak", "small". The Real Academia maintains the same definition and origin.
The viceroyalty of New Spain had prohibited Native Americans from riding or owning horses with the exception of the Tlaxcaltec nobility and other allied chieftains and their descendants. However, cattle raising required the use of horses, for which farmers would hire cowboys that were prefereably mestizo and rarely Indians. Some of the requirements for riding a horse were that one had to be employed by a plantation, had to use saddles that differed from those in the military, and had to wear leather clothing from which the term "cuerudo" (Leathered one) originated.
