Children in the Global South continue to be affected by social disadvantage in our unequal post-colonial world order. With a focus on working-class children in Latin America, this book explores the challenges of promoting children's rights in a context of decolonization. Liebel and colleagues give insights into the political lives of children and demonstrate ways in which the concept of children's rights can be made meaningful at the grassroots level. Looking to the future, they consider how collaborative research with children can counteract their marginalization and oppression in society.
