Circa 1000 AD, Proto-Eastern Algonquian emerged in what is now southern Ontario, and east, where the daughter Eastern Algonquian languages later spread from Atlantic Canada south to North Carolina. This period is marked by small-scale migrations into New England, likely introducing the beginnings of Three Sisters agriculture and influences of Iroquoian pottery. Since there is not evidence of large migrations, the spread of Eastern Algonquian seems to be more to the culturally advanced migrants triggering language shift since the last large movement of populations was during the Archaic Period (8000–2000 BC).
