What are the causes and consequences of colonial rule? This introduction to the special issue “Comparative Politics of Colonialism and Its Legacies” surveys recent literature in political science, sociology, and economics that addresses colonial state building and colonial legacies. Past research has made important contributions to our understanding of colonialism’s long-term effects on political, social, and economic development. Existing work emphasizes the role of critical junctures and institutions in understanding the transmission of those effects to present-day outcomes and embraces the (...) idea of design-based inference for empirical analysis. The four articles of this special issue add to existing research but also represent new research trends: increased attention to the internal dynamics of colonial intervention; noninstitutional transmission mechanisms; the role of context conditions at times of colonial intervention; and a finer-grained disaggregation of outcomes, explanatory factors, and units of analysis.
