الملخص	Set-theoretic multimethod research (SMMR) integrates the cross-case logic of Qualitative Comparative Analysis with the within-case logic of process tracing. After QCA identifies the combinations of conditions that are necessary or sufficient for an outcome, SMMR uses the resulting solution terms to classify cases — typical, deviant, individually irrelevant — and to select cases for in-depth process tracing. Codified by Carsten Schneider and Ingo Rohlfing, it grounds the choice of cases and the search for mechanisms in set theory, so cross-case and within-case inference reinforce one another within a single, coherent framework.	Comparative historical analysis (CHA) is a macro-causal research tradition that explains large-scale outcomes — revolutions, regime change, welfare states, development paths — by systematically comparing a small number of cases reconstructed in depth across historical time. It combines cross-case comparison with close attention to temporality: sequences, timing, critical junctures, and path dependence. Associated with Barrington Moore, Theda Skocpol, and codified by Mahoney and Rueschemeyer, CHA treats history not as background but as the medium through which causes operate.
