Obviously there is a lot more to the story of Indian/Puritan relations in New England than in the Thanksgiving stories we heard as children. Our contemporary mix of myth and history about the “First” Thanksgiving at Plymouth developed in the 1890s and early 1900s. Our country was desperately trying to pull together its many diverse peoples into a common national identity. To many writers and educators at the end of the last century and the beginning of this one, this also meant having a common national history. This was the era of the “melting pot” theory of social progress, and public education was a major tool for social unity. It was with this in mind that the federal government declared the last Thursday in November as the legal holiday of Thanksgiving in 1898.
In consequence, what started as an inspirational bit of New England folklore, soon grew into the full-fledged American Thanksgiving we now know. It emerged complete with stereotyped Indians and stereotyped Whites, incomplete history, and a mythical significance as our “First Thanksgiving.” But was it really our FIRST American Thanksgiving? ~ TEACHING ABOUT THANKSGIVING - Native American Culture
