A historian who compares world events from the classical era to those in the modern era is organizing history by thematic analysis or periodization. This approach allows for the exploration of recurring patterns, social structures, and cultural developments across different time periods. By drawing parallels and contrasts, the historian can highlight the evolution of political, economic, and social dynamics over time. This comparative method also helps to contextualize contemporary issues within a broader historical framework.
