Europe is a place of free movement among nations—or is it? The Schengen area, established in 1985 and today encompassing twenty-nine European countries, allows people, goods, and capital to cross borders without restraint. Schengen transformed European life, advancing both a democratic project of transnational citizenship and a neoliberal project of international free trade. But the right of free movement always excluded non-Europeans, especially migrants of color from former colonies of the Schengen states. In Europe without Borders, Isaac Stanley-Becker explores the contested creation of free movement in Schengen. Schengen laid the groundwork for the making of a single market and the founding of the European Union. Yet its emergence is one of the great untold stories of modern European history, one hidden in archives long embargoed. Stanley-Becker is among the first to have access to records of the treatymaking and Europe without Borders offers a pathbreaking account of Schengen's creation. Stanley-Becker argues that Schengen gave a humanist cast to a market paradigm; but even in pairing the border crossing of human beings with the principles of free-market exchange, this vision of free movement was hedged by alarm about foreign migrants. Meanwhile, these migrants—the sans-papiers—saw in the promise of a borderless Europe only a neocolonial enterprise.
