This document provides an overview of the nature, scope, and historical development of comparative politics. It discusses how comparative politics evolved from early classifications of political systems by Aristotle to include a wider range of countries and political phenomena. Key developments include: the rise of behavioralism in the 1950s which expanded the scope beyond institutions; studies of newly independent countries in the post-WWII era; and more recent trends like globalization challenging early modernization models. The document examines how the field has been shaped by changing contexts, ideas, and the geographical and conceptual boundaries of comparative analysis over time.
