Which Native American tribe made a peace treaty with the Pilgrims in 1620 under their leader Massasoit?

The Wampanoag tribe, under the leadership of Massasoit, entered into a peace treaty with the Pilgrims in 1620. This treaty was significant because it established a mutual agreement of cooperation and support between the Wampanoag people and the newly arrived Pilgrims, allowing for the two groups to work together for their mutual benefit.

Massasoit sought this alliance as a means to strengthen his tribe against rival groups and to navigate the newly encountered European settlers. The treaty laid the groundwork for the famous First Thanksgiving celebrated in 1621, where both the Wampanoag and the Pilgrims came together to share in the harvest.

In contrast, the Iroquois, Sioux, and Shawnee tribes had distinct cultures and territories, and did not participate in this specific treaty with the Pilgrims. The Iroquois Confederacy was located primarily in what is now New York, the Sioux were primarily in the Great Plains, and the Shawnee were originally in the Ohio Valley. Each of these groups had their own complex relationships and political structures that did not involve Massasoit or the Pilgrims, making the Wampanoag's treaty particularly notable in the context of early colonial history.
