In the western countries, the basis of studies of “comparative law” that started in 17th century aims for mutual legal solutions in a way that analyzes and compares the norms of several legal systems. Despite the gradual convergence of the systems, legal academicians have been avoiding the chance for a long time. Through the remarkable meetings of Roscoe Pound Comparative Law Studies in Paris, 1901 and the U.S., 1919, the idea of creating mutual norms that can be applied to several legal systems is accepted. Following that, “Comparative Law” became a department and a research area in law faculties. Comparative law is a frequently emphasized and growing area, especially in recent years. The system simply looks for a research, comparison of different cultures and the best possible compatibility in a world where the concepts of “far” and “close” or “local” and “foreigner” constantly and widely change. This field of science has an important role on expanding the general knowledge of law and the progress of law as a field of study. Overall, it provides a better understanding on national institutions as well as it contributes to those institutions in practice. A glimpse on comparative law reveals that it contributes to any area of law, from civil law to commercial law and from criminal law to social security law.
