The systematic study of how political institutions, customs, and practices vary across different societies and historical periods, looking for patterns and explanations rather than treating each case in isolation. Montesquieu's Spirit of the Laws was one of the founding works; Tocqueville's Democracy in America applied the comparative method to study American democratic society as a laboratory for understanding democratic life in general. Comparative politics is now a major field within political science.
