The Pilgrims of Plymouth Colony sign a peace treaty with Massasoit of the Wampanoags.

The Wampanoag , also rendered Wpanak, are a Native American people. They were a large confederation of at least twenty-four known, named tribes in the 17th century, but today Wampanoag people encompass five officially recognized tribes. The Mashpee Wampanoag Tribe and the Wampanoag Tribe of Gay Head in Massachusetts are federally recognized, and the Chappaquiddick Wampanoag Tribe, Herring Pond Wampanoag Tribe, Assawompsett-Nemasket Band of Wampanoags, and Pocasset Wampanoag Tribe are recognized by the Commonwealth of Massachusetts. They lived in southeastern Massachusetts and Rhode Island in the beginning of the 17th century, at the time of first contact with the English colonists, a territory that included the islands of Martha's Vineyard and Nantucket. Their population numbered in the thousands; 3,000 Wampanoag lived on Martha's Vineyard alone.

From 1615 to 1619, the Wampanoag suffered an epidemic, long suspected to be smallpox. Modern research, however, has suggested that it may have been leptospirosis, a bacterial infection which can develop into Weil's syndrome. It caused a high fatality rate and decimated the Wampanoag population. Researchers suggest that the losses from the epidemic were so large that colonists were able to establish their settlements in the Massachusetts Bay Colony more easily. More than 50 years later, King Philip's War (16751676), led by Metacom, chief sachem of the Wampanoag people, and his allies against the colonists resulted in the death of 40 percent of the surviving tribe. Many male Wampanoag were sold into slavery in Bermuda or the West Indies, or on plantations and farms run by colonists in New England.

The tribe largely disappeared from historical records after the late 18th century, although its people and descendants persisted. Survivors continued to live in their traditional areas and maintained many aspects of their culture, while absorbing other peoples by marriage and adapting to changing economic and cultural needs in the larger society. Jessie Little Doe Baird, a member of the Mashpee Wampanoag Tribe, founded the Wpanak Language Reclamation Project in 1993.

The Pilgrims, also known as the Pilgrim Fathers, were the English settlers who came to North America on the Mayflower and established the Plymouth Colony in what is today Plymouth, Massachusetts, named after the final departure port of Plymouth, Devon. Their leadership came from the religious congregations of Brownists, or Separatist Puritans, who had fled religious persecution in England for the tolerance of 17th-century Holland in the Netherlands.

They held many of the same Puritan Calvinist religious beliefs but, unlike most other Puritans, they maintained that their congregations should separate from the English state church, which led to them being labeled Separatists. After several years living in exile in Holland, they eventually determined to establish a new settlement in the New World and arranged with investors to fund them. They established Plymouth Colony in 1620, where they erected Congregationalist churches. The Pilgrims' story became a central theme in the history and culture of the United States.
