In this Sept. 14, 2014 photo, a charro or Mexican cowboy, attempts to bring down a bull by pulling his tail while riding on a horse; a move called "coleadero" or "steer tailing" during a "charreria," the Mexican version of a rodeo, in Mexico City. For the charro, his horse is as inseparable from himself as it is from the history of Mexico. We were conquered by horses, we gained our independence with horses, we made our Revolution with horses and we continue to love horses, said Daniel Flores Yeverino, 73, who began learning the skills of a charro when he was about 5 years old.

Other breeds such as Arabians are viewed as too high-strung for the demands of charreria. (AP Photo/Marco Ugarte)
