As suggested by previous research, the school systems and their steering documents played a significant role in the nation-building process during the 19th century. In this chapter, I study the policies and curricula that were enacted in Denmark, Norway, and Sweden 1805–1905 through the concepts of the "nation", and of "Scandinavia". I argue that the school systems in the studied countries became more nation-oriented towards the last decades of the 19th century. Meanwhile, the use of the concept of "Scandinavia" increased simultaneously in policies and curricula, especially in the secondary school systems in all countries. However, a shared Scandinavian identity does not seem to compete with the identity of the nation.
