The intersection of childhood and rulership has a long history. This chapter compares examples of child kingship across Europe before 1050 with cases between the eleventh and thirteenth centuries. It illustrates how structural developments in society, culture, politics and law brought greater political stability to a child’s rule during the central Middle Ages. Over this period, cultural attitudes towards violence were changing, practices of succession and inheritance were evolving, and ideas around marriage, illegitimacy and queenship were shifting. Such developments fundamentally altered the court environments into which royal children were born, the political context within which they succeeded, and the practicalities and precarities of their early experiences of rulership. This chapter examines aspects of violence, succession and queenship in turn before, in the fourth and final section, arguing for the need to revise claims of Germany’s exceptional ‘rejection’ of child kingship. While there are meaningful differences in how children were incorporated within systems and practices of kingship, this chapter suggests divergences between kingdoms should not be exaggerated.
