Petun

The Petun (from French: ), also known as the Tobacco people or Tionontati (Dionnontate, Etionontate, Etionnontateronnon, Tuinontatek, Dionondadie, or Khionotaterrhonon) ("The people of the place where the mountain stands"), were an indigenousIroquoian people of the woodlands of eastern North America. Their traditional homeland was south of Lake Huron's Georgian Bay, in what is today's Canadian province of Ontario.

The Petun were closely related to the Wendat, or Huron. Similar to other Iroquoian peoples, they were structured as a confederacy. One of the less numerous Iroquoian peoples when they became known to Europeans, they had eight or nine villages in the early 17th century, and are estimated to have numbered around 8,000 before European contact.

A number of epidemics were documented in Huron–Petun societies between 1634 and 1640, which have been linked to the arrival of French missionaries and traders. The epidemics decimated their population. Although they each spoke Iroquoian languages, they were independent of the Five Nations of the Iroquois Confederacy (Haudenosaunee), based south of the Great Lakes in present-day New York State. The powerful Iroquois sent raiding parties against the smaller tribes in 1648–1649 as part of the Beaver Wars associated with the lucrative fur trade, and virtually destroyed them. Some remnant Petun joined with refugee Wendat (Hurons) to become the Wyandot.
