The booklet Mourt's Relation (full title: A Relation or Journal of the Beginning and Proceedings of the English Plantation Settled at Plimoth in New England) was written primarily by Edward Winslow, although William Bradford appears to have written most of the first section. Written between November 1620 and November 1621, it describes in detail what happened from the landing of the Mayflower Pilgrims on Cape Cod (became Provincetown Harbor), through their exploring and eventual settling of Plymouth Colony; the book describes their relations with the surrounding native Americans, up to what is commonly called the first Thanksgiving and the arrival of the ship Fortune in November 1621. Mourt's Relation was first published and sold by John Bellamy in London in 1622. This significant tract has often been erroneously cited as "by George Morton, sometimes called George Mourt" (hence the title "Mourt's Relation").
