    Sammanfattning : This thesis aims to study the level and scale of literacy as it expanded in Viking towns during the 8th-12th century. In order to get an understanding of this spread, I have worked with two case-studies of Viking towns, as they were founded and prospered during and by the end of the Viking Age in Sweden; the town of Birka located in Björkö Island in Lake Mälaren, and the town of Sigtuna located in the province of Uppland, in central Sweden.
