They helped the Pilgrims, who arrived in the fall of 1620, survive at their new Plymouth Colony. The Wampanoag gradually lost their lands during the period of European colonization through land cessions and violent conflict with white settlers. The documentary Natives of the Narrowland (1993), narrated by actress Julie Harris, shows the history of the Wampanoag people through Cape Cod archaeological sites. In 1974, the Mashpee Wampanoag Tribal Council was formed to articulate the concerns of those with Native American ancestry. They petitioned the federal government in 1975 and again in 1990 for official recognition of the Mashpee Wampanoag as a tribe. In May 2007, the Wampanoag tribe was federally recognized. History European exploration Cape Cod was a landmark for early explorers. It may have been the "Promontory of Vinland" mentioned by the Norse voyagers (985–1025). The Manomet River area (taken up by the western end of the Cape Cod Canal in the early 20th century) is claimed by some to have been visited by Leif Eiriksson, and a stone wall discovered in Provincetown in 1805 is also claimed to have been built by his younger brother Thorvald Eiriksson around 1007 AD, when the keel of his ship was repaired in the harbor, according to Norse sagas. He was killed later in the same journey, and is said to have been returned to this spot for burial. However, there is no tangible support of the presence of Norse voyagers in Cape Cod, and the view is not generally accepted by archaeologists or historians. Giovanni da Verrazzano approached it from the south in 1524. He named Martha's Vineyard Claudia, after Claude of France, the wife of Francis I of France. In 1525, Portuguese explorer Estêvão Gomes called it Cabo de la Arenas while sailing under the Spanish crown. In 1602, Bartholomew Gosnold named the tip Cape Cod, the surviving term and the ninth oldest English place-name in the U.S. Samuel de Champlain charted its sand-silted harbors in 1606, and Henry Hudson landed there in 1609. Captain John Smith noted it on his map of 1614, and at last the Pilgrims entered the "Cape Harbor" and – contrary to the popular myth of Plymouth Rock – made their first landing near present-day Provincetown on November 11, 1620. Nearby, in what is now Eastham, they had their first encounter with Native Americans. European settlement Cape Cod was among the first places settled by
