Final answer:
William Penn established a long-lasting peace with Native American leader Tamanend of the Lenni Lenape tribe, creating a fair and mutually respectful relationship.
Step-by-step explanation:
William Penn, adhering to the principles of Quakerism, especially pacifism, sought to establish amicable relations with the Native American peoples upon arriving in the New World. Penn crafted a covenant with the Lenni Lenape (Delaware) tribe by purchasing their land fairly instead of resorting to force. Additionally, a significant treaty was signed in 1701 with the Susquehannocks aimed at preventing conflict. These diplomatic efforts resulted in over fifty years of peace between the colony of Pennsylvania and the indigenous population during its formative years. Notably, a famous depiction of this peaceful negotiation is captured in 'The Treaty of Penn with the Indians,' painted by Benjamin West, which represents the 1683 treaty signed by Penn and the chief of the Lenape Turtle Clan.
