Comparative law is the study of differences and similarities between the law of different countries. More specifically, it involves study of the different legal systems in existence in the world, including the common law, the civil law, socialist law, Jewish Law, Islamic law, Hindu law, and Chinese law. It includes the description and analysis of foreign legal systems, even where no explicit comparison is undertaken. The importance of comparative law has increased enormously in the present age of internationalism, economic globalization and democratization.
