This paper addresses the role of global migration and the nature of national borders within the co-constitution of class and race. We begin with Marx’s critique of the value-form – a critique that rests upon a distinction between the ‘essence’ of social reality and its immediate appearances. The paper elaborates how Marx’s understanding of the emergence of a society based upon generalised commodity production leads to a certain conception of the ‘political state’ and citizenship – and thus borders and national (...) belonging. This reveals the distinctive territorial forms of capitalism vis-à-vis those found in pre-capitalist societies, and moves us away from transhistorical conceptions of borders and the nation-state. In the second half, the paper turns to look at what this conception of borders and migration might mean concretely for how we think about the co-constitution of race and class today. Here the focus is on three crucial aspects of the contemporary world market: (1) the relationship between the cross-border movements of labour and processes of class formation, (2) migration and the determination of the value of labour-power, and (3) coercive and unfree labour.
