Horse racing was the main event. The typical farmer did not own a horse in the first place, and racing was a matter for gentlemen only, but ordinary farmers were spectators and gamblers. Selected slaves often became skilled horse trainers. Horse racing was especially important for knitting together the gentry. The race was a major public event designed to demonstrate to the world the superior social status of the gentry through expensive breeding, training, boasting, and gambling, and especially winning the races themselves. Historian Timothy Breen explains that horse racing and high-stakes gambling were essential to maintaining the status of the gentry. When they publicly bet a large sum on their favorite horse, it told the world that competitiveness, individualism, and materialism where the core elements of gentry values.
