Scandinavism (Danish: skandinavisme; Norwegian: skandinavisme; Swedish: skandinavism; Icelandic: skandinavismi), also called Scandinavianism or pan-Scandinavianism, is an ideology that supports various degrees of cooperation among the Scandinavian countries. Scandinavism comprises the literary, linguistic and cultural movement that focuses on promoting a shared Scandinavian past, a shared cultural heritage, a common Scandinavian mythology and a common language or dialect continuum (from the common ancestor language of Old Norse) and which led to the formation of joint periodicals and societies in support of Scandinavian literature and languages. The movement was most popular among Danes and Swedes.
