Laurentian, or St. Lawrence Iroquoian, was an Iroquoian language spoken until the late 16th century along the shores of the Saint Lawrence River in present-day Quebec and Ontario, Canada. It is believed to have disappeared with the extinction of the St. Lawrence Iroquoians, likely as a result of warfare by the more powerful Mohawk from the Haudenosaunee or Iroquois Confederacy to the south, in present-day New York state of the United States. St. Lawrence Iroquoians The explorer Jacques Cartier observed in 1535 and 1536 about a dozen villages in the valley between Stadacona and Hochelega, the sites of the modern cities of Quebec City and Montreal. Archeologists have unearthed other villages farther west, near the eastern end of Lake Ontario. St. Lawrence Iroquoians lived in villages which were usually located a few kilometres (miles) inland from the Saint-Lawrence River, and were often enclosed by a wooden palisade. Up to 2000 persons lived in the larger villages. By the time the explorer Samuel de Champlain arrived in 1608, however, he found no trace of the Iroquoians visited by Jacques Cartier some 75 years earlier. Scholars have developed several theories to explain the complete disappearance of the St. Lawrence Iroquoians, among them devastating wars waged by the Mohawk from the south, epidemics of Old World infectious diseases, or migration towards the Great Lakes region. Archeological evidence points most strongly to devastating wars with neighbouring Iroquoian tribes, the Huron and the nations of the Iroquois League, especially the Mohawk. Several dialects of Laurentian may have existed in the 16th century in the St. Lawrence River valley. The sparse records made by Jacques Cartier during his voyages cannot be considered conclusive, and the Laurentians may have spoken several distinct languages. A few Laurentian words are still in use today as toponyms: most notably the word canada, meaning "village" in Laurentian. Jacques Cartier used the word to describe both the region and the river that crosses it.
