In so many ways! To my mind, horses have made a bigger impact on human society than any other animal.
Horses provided the first means of fast travel. This sped up migration, trade, and communication between cultures. They helped languages and cultures spread around
the world. They helped people do work, from plowing fields to hauling goods. And horses contributed to human status, religion, and sports.
Horses have also played a critical role in warfare. Some of the major empire builders of the world—Alexander the Great, Attila the Hun, Genghis Khan—were able to
expand their vast territories through the use of cavalries.
