"The Plains Indians lived in North America before the Europeans came. Since they had no horses, the Plains Indians traveled on foot. To hunt buffalo, they would surround a herd and shoot the buffalo with bows and arrows. This changed when Spanish explorers came to North America and brought horses with them. Now the Plains Indians hunters were able to ride horses and follow buffalo over long distances. They carried tepees with them and set up camps. The hunters could kill buffalo and pull them back to camp using their horses. Later, guns again changed the way that Plains Indians hunted."
