Learn how wild mustangs were first introduced to America and how they still roam free today. On the North American plains, wild mustangs have roamed for generations . . . shaping human history and struggling to survive it. For the Spanish, they were a tool of conquest. For Native Americans, they brought on a new way of life where horsemanship and horse-trading were central. And for the entire world, wild mustangs became a renowned wonder of the American West. There are still thousands of mustangs in the wild today, but they struggle to survive in an ever-changing landscape and their future is by no means guaranteed.
