Over the last two decades, fighting modern slavery and human trafficking have become a cause célèbre. Yet, large numbers of researchers, nongovernmental organizations, trade unions, workers, and others who would seem like natural allies of the fight against modern slavery and trafficking are hugely skeptical of these movements. They object to anti-slavery and anti-trafficking framings of the problems, and are skeptical of the "new abolitionist" movement. Why? In this Introduction, we explain how our edited book tackles key controversies surrounding the anti-slavery and anti-trafficking movements and scholarship head-on. We have assembled champions and sceptics of anti-slavery to explore the fissures and fault-lines that surround efforts to fight modern slavery and human trafficking today. These include: whether efforts to fight modern slavery displace or crowd out support for labor and migrant rights; whether and to what extent efforts to fight modern slavery mask, naturalize, and distract from racial, gendered, and economic inequality; and whether contemporary anti-slavery and anti-trafficking crusaders’ use of history are accurate and appropriate.

This chapter traces how historical analogies have enabled the use of the terms slavery and abolition in both the anti-trafficking and the anti-incarceration communities. By placing the often-contradictory approaches these two communities bring to the history of slavery, we trace how a belief in historical progress and an emotional investment in the power of innocence – both concepts embedded in our understanding of childhood – have helped to forge vexed and contradictory definitions of both slavery and freedom. Ultimately we argue that the complex work of historical analogy requires us to imagine history, and the solutions we create in response to history, outside of a developmental model that views the degradation of enslavement a stage we can outgrow or discard.
