Research on the welfare state often examines social policies in democratic regimes separately from social policies in authoritarian regimes. Two bodies of research have emerged, as the extant literature views these political systems as sufficiently distinct to merit the division of analysis. In this article, we challenge the existing approach by showing that differing regime types can indeed be analysed together. By looking for patterns of similarities, rather than differences, we bring the two literatures into conversation and show how a common factor can trigger social policy expansion in both regime types. Using case studies of India and China, the two most populous democratic and authoritarian regimes, this article illustrates how the expansion of policies that serve low-income groups – India’s Mahatma Gandhi National Rural Employment Guarantee (NREGA) and China’s Minimum Livelihood Guarantee Scheme (dibao) – were both prompted by social mobilisation.
