The 13th volume of The Romanian Journal for Baltic and Nordic Studies reflects some of the research presented at the 12th International conference on Baltic and Nordic studies titled “Rethinking multiculturalism, multilingualism, and cultural diplomacy in Scandinavia and The Baltic Sea Region,” which will be held on May 27-28, 2021, under the auspices of the Romanian Association for Baltic and Nordic Studies. RethinkMulti-Kulti2021 was called to reflect on multiculturalism, multilingualism, and cultural diplomacy in Scandinavia and the Baltic Sea Region 10 years after German Chancellor Angela Merkel predicted the end of German multicultural society. Many politicians with Conservative leanings praised the confirmation that the half-century-cherished multi-kulti “utterly failed,” and far-right gurus interpreted it as an omen. Furthermore, Merkel’s track record as a committed democratic-minded politician, EU leader, and proponent of migrant integration has garnered near-universal support for this argument. Furthermore, in academia, Merkel’s assertion has never been adequately questioned, but rather taken for granted. Meanwhile, policies governing multiculturalism and multilingualism in the EU and EEA have been stuck in a rut, particularly in what Fareed Zakaria properly refers to as illiberal democracies. The purpose of the conference was not to resurrect the political objective behind multi-kulti, but rather to critically reassess the role of multiculturalism, multilinguism, and cultural diplomacy from the viewpoint of Scandinavia and the Baltic Sea Region. We see Scandinavia and the Baltic Sea Region as interrelated and partially overlapping by a plethora of historical, cultural, and social channels, hence papers dealing with multiculturalism, multilinguism, and cultural diplomacy as reflected in these regions and wider Europe were planned. Papers on connections, liaisons, affiliations, divergences, animosity, legal or de facto statuses of cultures and languages in Scandinavia and the Baltic Sea Region were also presented during the conference. How multilingualism, multiculturalism, and cultural diplomacy prospered or muddled through transitions from liberal nations to far-right or far-left governments and back were also addressed.
