Comparative Law: A Very Short Introduction aims to offer a concise introduction to comparative law-its objectives, methods, concepts, and uses. After an overview of the fundamental definitions, key concepts, and basic lexicon of the discipline, the book proposes an analysis of the most successful techniques adopted in legal comparison for mapping the world’s legal systems and for explaining legal change and diffusion of law, also giving a concise description of the legal traditions of the world.

It also offers an account of the competing approaches adopted over time in comparative endeavors, from functionalism to culturalism and postmodernism, and highlights the different emphasis placed by each of these approaches on commonalities, faith in universal law and convergence, or on divergence and irreducible differences. Finally, the book provides listeners with an understanding of the practical use of comparative law, describing how legal comparison is employed both in lawmaking and in adjudication, supplementing legal reasoning and interpretation.
