Copies of the agreement, to be signed by participating merchants, are circulated beyond the Province of Massachusetts Bay to other colonial provinces in New England.
November 14 – The Timucua Indian tribe, native to central Florida, becomes extinct with the death of the last speaker of the Timucuan language, Juan Alonso Cabale.
