Sometimes known as the "sport of kings," polo has long been associated with royalty. It's a fairly strenuous sport, but one that also requires dexterity and strategy. For the British Royal Family, many generations of men have played the sport, and the events and matches are often invitation-only.
Often, the most interesting aspect of polo is the guest list itself. When then-Prince Charles started dating Diana, for example, she began appearing as his guest at various matches. The below photos provide some off-the-cuff, casual moments from royalty and their families—a behind-the-scenes look at some of the most famous people in the world. Below, candid photos of the Royal Family at polo matches.
