The introduction of the horse by the Spanish in the late 17th century profoundly transformed the lives of Great Plains peoples, so much so that historians often divide the region's history into pre- and post-horse periods.123

Key changes included:

  • Increased Mobility and Hunting: Horses replaced dogs as the primary draft animals and allowed tribes to travel significantly greater distances. This mobility enabled hunters to keep pace with bison herds, making the hunt more efficient and rewarding compared to earlier pedestrian methods, such as driving animals over cliffs.4562
  • Economic Prosperity: The ability to follow bison herds across the grasslands supported a more nomadic lifestyle and boosted food supplies, leading to an era of unprecedented prosperity for many nations.436
  • Political Power: Mastery of equestrian warfare and hunting techniques helped groups like the Comanche and Sioux achieve significant political influence.2
  • Cultural Shifts: Tribes adjusted their annual cycles to match the movements of the bison, gathering in large groups during the summer and dispersing into smaller bands during the rest of the year.4
