This book presents an integral, cross-cultural reflection on the social reality of children's rights and citizenship and contributes to establishing for the first time a social theory of children's rights. Based on internationally discussed theories and worldwide social research on the conceptualization and implementation of children's rights, this book gives an insight into new perspectives on the history and different concepts of children's rights in a contextualized and localized manner. Furthermore, it explains how children's rights can be understood as relevant and attractive by children themselves living in different social and cultural contexts.
