Most slave trades were abolished during the 19th century yet there remain millions of people in slavery today, amongst them approximately 210 million children in slavery, trafficked, in debt bondage and other forms of forced labour. This groundbreaking book, drawing on experience worldwide, shows how children remain locked in slavery, the ways in which they are exploited and how they can be emancipated. Written for policy and political actors, academics and activists, it reminds us also that all are implicated in modern childhood slavery – as consumers – and need both to understand its causes, and act to stop it.
