Conversation so far:
What happened at the start of the 18th century?
At the beginning of the 18th century, more organized violence than in previous decades occurred between the Native Americans involved in the deerskin trade and white settlers.
What tribes were involved?
Creeks and Cherokees.
What European countries did they trade with?
European colonists.
What furs were traded?
deerskins.
What was the trade between the Native Americans and Colonists like?
The British promoted competition between tribes, and sold guns to both Creeks and Cherokees.
What came as a result of this competition?
This competition sprang out of the slave demand in the southeast - tribes would raid each other and sell prisoners into the slave trade of the colonizers.
How did this affect the trade?
Guns and other modern weapons were essential trading items for the Native Americans to protect themselves from slave raids.
What else came of it?
The need for Indian slaves decreased as African slaves began to be imported in larger quantities, and the focus returned to deerskins.
What followed the slave demand reduction?
Indians who were not able to pay their debt were often enslaved.
The practice of enslavement extended to the wives and children of the Yamasees in debt as well.
How did this affect the people or trade?
This process frustrated the Yamasees and other tribes, who lodged complaints against the deceitful credit-loaning scheme traders had enforced.

Question: What came of their complaints?
