What was the most important thing the Plains Indians got from the Europeans?

The most important resource the plains Indians got from the Europeans was the horse (which had become extinct in the western hemisphere by 10,000 b.c.e.) Cortes reintroduced the horse to the Americans after the 16th century. By the 18th century, the plains Indians had made them a large part of their culture. Mounted Indians could run down buffalo instead of staking them on foot. They could move and fight more effectively, as well as traveling with more possessions and larger tepees.
