Mustangs are one of the most wildest horses in the world. 'Mustang' in Spanish means running wild. It all started when a bunch of Spanish moor horses where brought to Mexico by Captain Cortez. There were no horses in America until he brought his Spanish moor horses. Some of the younger moor horses were restless. These horses weren't very good to be war horses. Some of them started to wander away from their owners and make herds of their own in the valleys. They weren't missed much (partly because they weren't very good for war horses). They kept on wandering and starting their own herds. The Spanish called them Mustangs (running wild). These Mustangs changed from their Spanish moor ways into wild Mustangs. Soon there were spots and patches of different colors mixed into the Mustangs, instead of just the plain coat color of the moor horses.
Indians were afraid of the Spanish and of their horses. The Indians were made into slaves and they were very scared of the 'monsters' (Spanish riders). But then they started to notice that the riders and horses where not one thing. They watched closely how the Spanish mounted and dismounted their horses. Some of the Indians even wanted to ride these horses and some ran away on the Spanish moor horses. Soon, many Indians learned that horses were their friends. The Indians found many of the wandering Mustangs and used them for many things. They became better riders than the Spanish themselves! They often rounded up wild horses and then herd out a Mustang that would catch their eye.
When the settlers moved in they also started rounding up the Mustangs. The Mustangs were usually used for cutting, but when there were mustangs that couldn't be broke, they were often used for rodeos. As soon as a rider would get himself into the saddle, the Mustang would go mad, bucking, kicking, swinging around to the right and left. And he would soon buck off his rider sending him into the dust!
Later they would round the horses with planes. They would be driven into a corral to be used for rodeo buckers, cow ponies, or worst of all, meat. But sometimes some lucky Mustangs would escape and run wild again.
