The correct answer is: The two groups were at peace after signing treaties based on trust.
The colony of Pennsylvania was given to William Penn on March 4, 1681 by King Charles II; William Penn received the colony as a payback for a debt that his father had with the crown. Penn wrote, while still in England, his first Frame of Government, in which he promised certain rights to the citizens of Pennsylvania. One of his main concerns was to create a fair and just relationship with the native Americans. This extreme tolerance led to healthier relationships with the natives of the local tribes. He had no desire in taking away the land of the Native Americans, as a result, he wanted to negotiate trustworthy agreements to buy the land that belong to the natives.
The native tribe with which William Penn has the greatest relation was the Delaware tribe, he accepted to deal with them and bought them some land. With this, he showed the Delaware Indians that he did not wat to take away their lands in a dishonorable or illegal way. Penn also promised the Delaware tribe to deal with them fairly and honestly, making with these treaties a peaceful colony in which natives and colonists lived in peace.
