Who was the Wampanoag chief known for his interaction with the Pilgrims?

The Wampanoag chief known for his interaction with the Pilgrims was Massasoit. He played a crucial role in the early relationship between the Wampanoag people and the English settlers at Plymouth Colony. Massasoit established a diplomatic alliance with the Pilgrims, which was significant for the survival of the settlers in their first years. This alliance included mutual assistance and support, exemplified by the assistance the Wampanoag provided during the settlers' first winter. This early cooperation laid the groundwork for what is often idealized as the first Thanksgiving, where both groups came together to celebrate the harvest.

Metacom, also known as King Philip, was the son of Massasoit and is remembered for leading a rebellion nearly four decades later, which highlights the complex dynamics of Native American and settler relationships over time. Powhatan was a prominent chief in Virginia, relevant to a different group of settlers. Osceola was a leader involved in the Seminole Wars, which occurred much later in American history. Thus, the context of Massasoit's role and his direct engagement with the Pilgrims makes him the correct answer in this case.
