The use of horses by humans began roughly 5,500 years ago on the windswept grasslands of the Pontic- Caspian Steppe when a daring man (or a woman – we have no way of knowing) jumped on the back of a docile mare. Thus began the horse’s unrivalled historical influence across millennia to the present day. The horse dominated every facet of humanity—as a mode of transportation, a vehicle of trade, an essential farming tool, a status symbol, a formidable weapon of war, a source of energy, an agent of both lethal disease and lifesaving medicine, a participant in sport, and, of course, a steadfast and loyal companion. For most of us, horses are not part of our everyday, practical lives, and are instead relegated to entertainment and recreation through racing, rodeos, and equestrian or television shows and movies depicting bygone eras. But this is a relatively recent development as cars “unseated” the horse as the primary method of transportation a mere one hundred years ago. To demonstrate the profound historical impact of the horse on our global civilization, we are joined by Timothy Winegard, author of “The Horse: A Galloping History of Humanity.”
