Final answer:
The Jockey Club is associated with organizing, sponsoring, and promoting horse racing events. Horse racing has a historical significance as a sport and leisure activity entwined with gambling. It has seen transformations over the decades but experienced issues with diversity and inclusion, particularly concerning African American jockeys.
Step-by-step explanation:
The Jockey Club is an organization known for its association with horse racing. It organized, sponsored, and promoted events related to this sport. Horse racing has a long history and has been a notable aspect of various societies, serving as both a leisure activity and a sport with significant gambling associations.
During the late nineteenth century and the turn of the twentieth century, spectator sports, like horse racing, became big business in America. This change reflected a shift from informal local contests organized around gambling to more organized, professional spectator sports. Horse racing, though it had been criticized for encouraging gambling, remained a popular spectator sport and was associated with various social classes, including the upper classes in cities.
Noteworthy is the fact that African Americans, who once dominated the sport, faced exclusion from horse racing due to segregationist practices requiring membership in all-white jockey associations.
