Tóm tắt	Comparative historical archival research combines systematic examination of primary archival sources across two or more historical cases — nations, regions, institutions, or time periods — to identify causal patterns, structural similarities, and divergences that single-case histories cannot reveal. It is the method of choice when researchers want to explain why similar or different outcomes emerged across distinct historical contexts using documentary evidence.	Comparative case study is a qualitative research design in which two or more bounded cases are studied in depth and then systematically compared to identify similarities, differences, and patterns across contexts. Rooted in Yin's replication logic and Stake's multiple case framework, it is particularly suited to questions that ask how or why a phenomenon unfolds differently — or similarly — across distinct settings, populations, or time periods.
