 Kasaan was established by the Haida in protohistoric times or earlier, as part of a migration across Dixon Entrance, from Dadens and other villages of Langara Island, Haida Gwaii, to Dall Island and Prince of Wales Island.Beginning in the late 1700s, European and U.S. ships began regularly visiting and trading with Kasaan and the rest of the Haida.Most early visiting ships were part of the maritime fur trade.
