Latin American states took dramatic steps toward greater inclusion during the late twentieth and early twenty-first Centuries. Bringing together an accomplished group of scholars, this volume examines this shift by introducing three dimensions of inclusion: official recognition of historically excluded groups, access to policymaking, and resource redistribution. Tracing the movement along these dimensions since the 1990s, the editors argue that the endurance of democratic politics, combined with longstanding social inequalities, create the impetus for inclusionary reforms. Diverse chapters explore how factors such as the role of partisanship and electoral clientelism, constitutional design, state capacity, social protest, populism, commodity rents, international diffusion, and historical legacies encouraged or inhibited inclusionary reform during the late 1990s and early 2000s. Featuring original empirical evidence and a strong theoretical framework, the book considers cross-national variation, delves into the surprising paradoxes of inclusion, and identifies the obstacles hindering further fundamental change.
