Diplomacy is the art and practice of conducting negotiations between accredited persons (the diploma of the diplomat) representing groups or nations. It usually refers to international diplomacy, the conduct of international relations through the intercession of professional diplomats with regard to issues of peace-making, culture, economics, trade and war. International treaties are usually negotiated by diplomats prior to endorsement by national politicians.
