More on charros and charreadas from Wikipedia: "The charreada is the original rodeo developed in Mexico based on the working practices of charros or working hands. The modern events were developed after the Mexican Revolution when charro traditions were slowly disappearing. A charreada consists of nine events for men and one for women."
