In current debates about globalisation, open and borderless elites are often set in opposition to the immobile and protectionist working classes.

In this urgent, engaging work, historian Nicolas Delalande explores how international worker solidarity developed, what it accomplished in the nineteenth and twentieth centuries, and why it collapsed over the past forty years, to the point of disappearing from our memories.
