During the reign of Fath Ali Shah Qajar, Iran became a focal point for European countries, resulting in frequent visits by representatives and official ambassadors from these nations as well as neighboring states to the Qajar court. These extensive relations led to the implementation of specific protocols and ceremonies for welcoming, accommodating, and receiving ambassadors at Fath Ali Shah’s court. Some of these practices were derived from Iranian court traditions, while others were adapted to meet the demands of the time. This descriptive-analytical study aims to examine the ceremonies and protocols associated with receiving foreign ambassadors at the court of Fath Ali Shah Qajar, addressing the question of what protocols were observed and how these were influenced by external factors. The findings indicate that during the reign of Agha Mohammad Khan Qajar, there were no specific protocols or ceremonies for welcoming ambassadors. However, the courtiers of Fath Ali Shah, recognizing the necessity of managing foreign relations and the king’s penchant for elaborate court ceremonies, adapted and expanded upon existing Iranian court reception protocols to create lengthy and complex ceremonies for welcoming and receiving foreign ambassadors. These ceremonies were designed to both fulfill diplomatic obligations and showcase the grandeur and magnificence of the Iranian monarchy to foreign representatives. Nevertheless, the intervention of colonial powers led to alterations in traditional reception practices.
