Within the international society, law and diplomacy have always been complementary and interdependent. However, lawyers and diplomats deal with international issues differently, making them rivals to be the primary mode of international interaction. Diplomacy is the art and practice of conducting negotiations between representatives of states; it usually refers to international diplomacy, the conduct of international relations through the mediation of professional diplomats with regard to a full range of topical issues. Nations sometimes resort to international arbitration when faced with a specific question or point of contention in need of resolution. For most of history, there were no official or formal procedures for such proceedings. They were generally accepted to abide by general principles and protocols related to international law and justice. International law is the set of rules generally regarded and accepted as binding in relations between states and between nations. It serves as a framework for the practice of stable and organized international relations. Much of international law is consent-based governance. This means that a state member is not obliged to abide by this type of law, unless it has expressly consented to a particular course of conduct, or entered a diplomatic convention. Interdisciplinary courses, like diplomacy and international law, are designed to help one think critically about diplomatic and international legal issues in real-life contexts, while applying theory to practice and addressing some of the key questions facing the world today.
