but rather a methodological one: it focuses on "the how but does not specify the what of the analysis." Peter Mair and Richard Rose advance a slightly different definition, arguing that comparative politics is defined by a combination of a substantive focus on the study of countries' political systems and a method of identifying and explaining similarities and differences between these countries using common concepts. Sometimes, especially in the United States, the term "comparative politics" is used to refer to "the politics of foreign countries." This usage of the term is disputed. Comparative politics is significant because it helps people understand the nature and working of political frameworks around the world. There are many types of political systems worldwide according to the authentic, social, ethnic, racial, and social history. Indeed, even comparative constructions of political association shift starting with one country then onto the next. For instance, India and the United States are majority-rule nations; nonetheless, the U.S. has a liberal vote-based presidential system contrasted with the parliamentary system used in India. Even the political decision measure is more diverse in the United States when found in light of the Indian popular government. The United States has a president as their leader, while India has a prime minister. Relative legislative issues encourage us to comprehend these central contracts and how the two nations are altogether different regardless of being majority rule. This field of study is critical for the fields of international relations and conflict resolution. Near politics encourages international relations to clarify worldwide legislative issues and the present winning conditions worldwide. Although both are subfields of political science, comparative politics examines the causes of international strategy and the effect of worldwide approaches and frameworks on homegrown political conduct and working. History of the field Harry H. Eckstein traces the history of the field of comparative politics back to Aristotle, and sees a string of thinkers from Machiavelli and Montesquieu, to Gaetano Mosca and Max Weber, Vilfredo Pareto and Robert Michels, on to James Bryce - with his Modern Democracies (1921) - and Carl Joachim Friedrich - with his Constitutional Government and Democracy (1937) - contributing to its history. Two traditions reaching back to Aristotle and Plato Philippe C. Schmitter argues that the "family tree" of comparative politics has two main traditions: one, invented by Aristotle, that he calls "sociological constitutionalism"; a second, that he traced back to Plato, that
