The Protocol is an essential part of diplomatic practice, linked with history, royalty, religion, culture, and language. The protocol involves Etiquette on a local and international scale and the practice of good manners on a daily basis. It evolved as a result of old traditions in the early days of civilization; hospitality was extended to an arriving guest. Today it is particularly important because it doesn't only covers the ceremonial rules that are followed during the official functions and how to behave on these special occasions. But it also provides a set of established rules of courteousness that are to be respected in society.
