The horses were released and living in freedom they spread all the way to Nort America, especially to the south west. The Mustangs were found in packs in the United States.

it was forbidden for them to ride horses, it was an exclusive spanish activity.

Apache Indians were the first to discover they could use horses to go hunting. They learnt how to ride and the other American Indians soon discover the same. They hunted buffalos: riding horses made them faster and help them to lead the buffalos packs to wherever they wanted to, making hunting easier.
