Stein Rokkan (1921–1979) left behind him an unfinished, ambitious macro-historical research project aiming to explain mobilization sequences, democratic resilience, and party systems in 16 Western European countries. This article explicates the comparative methodology behind this project with reference to a philosophy of social science framework. The main features of the methodology are a series of intermediate, substantive, methodological elements in between formal theory (paradigms) and empirical observations. Each element is presented in detail: lists of variables, regional grid, typological-topological maps, and comparative case reconstructions. Problems due to under-specification of variables and ambiguities in Rokkan’s ideas about parsimonious systematizations are discussed, and two possible ways of revising the methodology are sketched. Among these, the contextualist option seems the most promising one.
