In international politics, protocol is the etiquette of diplomacy and affairs of state. It may also refer to an international agreement that supplements or amends a treaty.
A protocol is a rule which describes how an activity should be performed, especially in the field of diplomacy. In diplomatic services and governmental fields of endeavor protocols are often unwritten guidelines. Protocols specify the proper and generally accepted behavior in matters of state and diplomacy, such as showing appropriate respect to a head of state, ranking diplomats in chronological order of their accreditation at court, and so on. One definition is:
Protocol is commonly described as a set of international courtesy rules. These well-established and time-honored rules have made it easier for nations and people to live and work together. Part of protocol has always been the acknowledgment of the hierarchical standing of all present. Protocol rules are based on the principles of civility.—Dr. P.M. Forni on behalf of the International Association of Protocol Consultants and Officers.
There are two meanings of the word "protocol". In the legal sense, it is defined as an international agreement that supplements or amends a treaty. In the diplomatic sense, the term refers to the set of rules, procedures, conventions and ceremonies that relate to relations between states. In general, protocol represents the recognized and generally accepted system of international courtesy.
The term protocol is derived, via French and Medieval Latin, from the Greek word πρωτόκολλον protokollon "first glued sheet of or onto a papyrus-roll". This comes from the act of gluing a sheet of paper to the front of a document to preserve it when it was sealed, which imparted additional authenticity to it. In the beginning, the term protocol related to the various forms of interaction observed in official correspondence between states, which were often elaborate in nature. In course of time, however, it has come to cover a much wider range of international relations.
The rules of protocol to create space where meetings can take place.
As paradoxical as it may sound, the framework of protocol actually doesn’t limit space, it creates it. By ensuring a smooth organisation, participants in an event and especially those acting as host, can focus on the content of the event without having to worry about the unexpected.
The other side of protocol: its symbolic value.
Protocol also has a symbolic value. The events and rituals, for example, of the formal start of the parliamentary year and The Queen’s Speech in the United Kingdom are meant to symbolise the democratic values of the country. This is the case at every ceremony that more or less follows the same pattern, like the exchange of rings and vows at weddings or the receiving of a diploma at a graduation ceremony. Symbols add meaning to the community’s values but also credibility, strength and often also beauty.
The model by the sinologist Monica Bakker  has the rules on the left side, the symbols on the right side and the creation of trust and connection in the middle. The rules guarantee predictability and therefore offer the opportunity to create community. The symbolic side of the protocol is the story, so all of us participating in the event are able to understand the broader context of why we are here. Only if these two are applied in the right way, protocol is a facilitator of trust, connection and confirmation of the good relationship.
The challenge, however, is to balance between modernity and tradition. If the rules are applied too strictly, the event will become too formal and uncomfortable. Too casual and lacking focus is also not good and the use of too few rules will result in chaos. Also, too many symbols will make people laugh and when there is no symbolism, we will not be able to recognise the story and/or are able to relate to why we are attending the event.
