概要	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 legal analysis is a structured research method that examines how two or more legal systems — whether national, regional, or supranational — address a common legal problem. By placing rules, doctrines, and judicial decisions side by side, researchers identify convergences, divergences, and the underlying societal, historical, and political forces that shape legal solutions. The method is foundational to law reform, harmonisation efforts, treaty drafting, and academic legal scholarship.
