Often used as one of the clearest indications of status and identity in western art since Antiquity, portraits also served a similar purpose for ambassadors. Furthermore, documenting the physiognomy of ambassadors through portraiture was also regarded as a precautionary measure against espionage. Portraits were painted of European ambassadors sent to the Ottoman Empire as high-level officials that have attained great respectability; artists to which these portraits were commissioned strived to reflect not only the physiognomy of the ambassadors, but the power and authority of the state and the ruler they represented.
The Ottoman State's political, military, commercial, and cultural relations with European states gained momentum from the 18th century onwards. In turn, the visits Ottoman ambassadors paid to western countries accelerated the spread of the Turquerie fashion of the period. While portraits of Ottoman ambassadors painted by renowned artists of the countries to which they were assigned served to honor the Ottoman Sultan and his representative, they also nurtured the West's penchant for exoticism. There is no doubt that the ever-changing trends, fashions, as well as the purpose of diplomatic visits and political relations were reflected in the portraits. For example, while Kozbekçi Mustafa Ağa, who was sent to Sweden to collect debts, is portrayed standing -like a western emperor-, Yusuf Agâh Efendi, who left for England in the late 18th century as the first permanent ambassador of the Ottoman Porte, is depicted entirely in an eastern pose with the rosary beads he holds in his hand against a western background. When French Ambassador Comte de Vergennes commissioned portraits of himself and his wife in Ottoman attire per the Turquerie fashion, he was depicted in an eastern pose, thereby clearly emphasizing that he served as ambassador in İstanbul.
Paintings depicting the audience of European ambassadors at the Ottoman Palace constitute a special group of works that not only demonstrate a diplomatic event and reflect court traditions and officials in a range of attires, but they also act as portraits of foremost individuals, such as the sultan and the grand vizier. Borne directly out of and as a consequence of the realm of ambassadorial service, the best-known examples of this genre have been executed by Jean-Baptiste Vanmour.
