This chapter explains the treatment of mentality with respect to the monarchy and the church that were built up in Scandinavia in the high Middle Ages. In this way, it becomes possible to treat mentality in close connection with ideology. A main theme in most surveys of the Scandinavian countries until around 1300 is the growth of the state. The mental aspect of this development is illustrated clearly in The King's Mirror. The conflict between the old and the new attitude to a central authority emerges clearly from The King's Mirror. An important symbolic expression of the new ideology was royal unction and coronation which introduced in Norway, Denmark and Sweden in the 11th and 12th centuries. Courtly culture was an important medium of the far-reaching changes as a result of the victory of the state. The chapter also discusses the importance of Christianity, oral and visual preaching, and Christianity as a religion for the laity and the nobility.
