In recent years, socio-political crises have challenged democracy across South America. Social movements that succeeded in mobilising marginalised sectors are at the forefront of this turbulence, Ecuador's indigenous movement and the organisations of unemployed workers in Argentina being paradigmatic cases. Recent developments point to an intrinsic weakness of both indigenous and unemployed movements, in that democratic regimes have proved highly successful at ‘taming’ them. By comparing the two movements, in terms of their internal dynamics and interactions with the political system, this article argues that common characteristics that were crucial for successful mobilisation in the first place, at the same time, help explain their vulnerability to division and clientelist integration.
