There were ancient horses native to the Americas, but they went extinct prior to human civilizations being founded. The current mustang population of the American West, the Chincoteague Ponies and other feral horse populations are all descendants of horses and ponies brought over by the European explorers, settlers and conquistadors.

The original Spanish explorers brought horses to North America. Many of those horses were turned loose when the Spaniards returned to Spain and they intermingled with native horses (horses that came from China over the ice cap). The Mustang is the result of that interbreeding. The first importation of Spanish Arabian horses was in 1934 when James and Edna Draper (from California) imported the first purebred Arabian horses to the United States.
One could argue that all discovery is good, but at the same time, Columbus and other explorers brought diseases to north America that nearly wiped out the natives there. This is subjective.
