In fact, unlike in centuries gone by when war was common, diplomacy is what we understand today as the normal state of affairs governing international relations. And, in the modern era, diplomacy is conducted not only between nation-states, but also by a range of non-state actors such as the European Union and the United Nations. Diplomacy has probably existed for as long as civilisation has. The easiest way to understand it is to start by seeing it as a system of structured communication between two or more parties. Records of regular contact via envoys travelling between neighbouring civilisations date back at least 2500 years. They lacked many of the characteristics and commonalities of modern diplomacy such as embassies, international law and professional diplomatic services.
