The influx of African migrants into Europe in recent years has raised important issues about changing labor economies, new technologies of border control, and the effects of armed conflict. But attention to such broad questions often obscures a fundamental fact of migration: its effects on ordinary life. Affective Circuits brings together essays by an international group of well-known anthropologists to place the migrant family front and center.Moving between Africa and Europe, the book explores the many ways migrants sustain and rework family ties and intimate relationships at home and abroad. It demonstrates how their quotidian efforts on such a mass scale contribute to a broader process of social regeneration. The contributors point to the intersecting streams of goods, people, ideas, and money as they circulate between African migrants and their kin who remain back home.They also show the complex ways that emotions become entangled in these exchanges. Examining how these circuits operate in domains of social life ranging from child fosterage to binational marriages, from coming-of-age to healing and religious rituals, the book also registers the tremendous impact of state officials, laws, and policies on migrant experience. Together these essays paint an especially vivid portrait of new forms of kinship at a time of both intense mobility and ever-tightening borders.
