The Inuit of Labrador speak Inuktitut. This was only a spoken language until the arrival of Moravian missionaries in the eighteenth century. The Moravians introduced Christianity to the area, with a very disruptive impact on the Inuit belief system and way of life. They also recorded Inuktitut in writing, enabling the population to become literate in its own language, and resulting in its preservation, when many Indigenous languages died out because of the processes of colonisation.
