In this chapter, the authors aim to compare the Nordic societies in a broad fashion in the last 200 years in their process of “sailing” (with the implication of rough waters along the way) from social fragmentation to more inclusive welfare societies. The authors’ main goal is to examine the coevolution of economic, political, and fiscal factors among the Nordic societies in the long run by making use of recent longitudinal data sets. In this way, they can map out some key patterns that characterized the shift toward more peaceful and well-functioning societies. First, the authors focus on the process towards economic and political convergence that took place, with some exceptions, in the latter part of the 20th century. Second, they also examine how these processes of convergence translated into the realm of fiscal and social policies and to what extent they were related to decreasing levels of social fragmentation. The chapter shows that the paths towards welfare states were not uniform among the Nordic countries and that some of the pivotal forces and periods were connected to various types of crises, namely, that these were not processes that were smooth or inevitable. The chapter concludes with some general findings and a discussion of current-day problems among the Nordic societies from a comparative historical perspective.
