The articles in the explanatory dictionary contain information about the main categories of Roman law. The Dictionary reflects not only concepts related to Roman jurisprudence, but also the judicial principles of that time. If we carefully study the judicial principles of that time, we will find that most of these principles are practically applied at the present time in modern legislation. The Dictionary of Roman Law is designed both for professional lawyers, law students and persons mastering international law, and to a wide range of readers.
