The Preparation of Embassies and the Protocols Followed by Royal Portuguese Ambassadors in the Late Middle Ages

Résumé 0

Diplomatic correspondence and the information transmitted through letters of instruction, which gave diplomats the necessary support for the performance of their duties, have become a highly important subject in the study of medieval diplomacy. In documents of this type, we can find some quite remarkable and valuable information about what could or could not be said in diplomatic contexts, outlining the rituals, attitudes, and procedures that a diplomat was required to adopt in the course of his international mission. Together with the letters of instruction, diplomats also carried with them letters of credence (commonly known as credentials). These were the documents that the various monarchs gave to their legitimate representatives, and which were designed to be presented at the courts visited by each diplomatic mission. These letters were essential for guaranteeing the correct conduct of negotiations, since, besides presenting the diplomats and expressing the wish that they be afforded credence in their role, these documents also explained the purpose of their missions. Thus, letters of instruction and credence are fundamental tools that enable historians to complete the picture of external relations through the description that they provide of other aspects of communication and symbolic representation, which sometimes tend to go unnoticed in different types of documents. In order to better understand certain fundamental aspects of this analysis, we complemented the information obtained from the aforementioned documentation with data from other documentary sources that indicate some of the protocols that were used in dealings with princes and kings of other realms, as well as the specific characteristics that some of the royal counsellors should have.
