Between Scandinavians’ diaspora on the North Atlantic and their energetic participation on the Eastern Route is the lively activity and interactions with diverse cultures around the Baltic Sea – the mare nostrum of Baltic, Finnic, Sámi, Scandinavian and Slavic speakers. Sagas provide the richest early written sources not just for Scandinavian cultures but also for their interactions with other groups in this part of the world. In the spirit of these contacts and mobility, we will bring the 18th International Saga Conference to the eastern side of the Baltic Sea to be hosted in two countries, Finland and Estonia, with movement between them.
