"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."
