 Most of these events were later discontinued, although equestrian events have continued through the 2016 Summer Olympics, and now include team and individual dressage, three-day eventing and show-jumping.Competitors in the modern pentathlon event also have to complete an equestrian show-jumping course, but this is not part of the equestrian events.Modern-day Olympic equestrian events are rooted in cavalry skills and classical horsemanship, and through 1948, competition was restricted to active-duty officers on military horses.
