Stanisław August [Stanislaus Augustus] Poniatowski was elected king of Poland in 1764. Especially at the beginning of his reign, he was neither very popular with the nobility nor as influential as his rich family, the Czartoryski Familia. Therefore, he needed a formal portrait emphasizing the special significance of his person as the king of Poland and strengthening the conviction about the lawfulness of his rule, actually assumed with the considerable support of Russia. Moreover, European courts, for example in Vienna and Versailles, were interested in possessing a portrait of the new Polish king. The newly elected monarch sought a talented portraitist, familiar with the latest trends in Western European art, who would be able to paint a splendid formal portrait. He wished to entrust this task to Marcello Bacciarelli, an Italian painter who had stayed at the court of Augustus III the Saxon in Warsaw for several years, leaving in the country a large number of excellent portraits of aristocrats. The king did not want to be portrayed in armor, but in the formal dress that he was wearing during the coronation ceremony: a coat lined with ermine fur, decorated with Polish eagles, a frock coat and trousers, with his hand rested against the baton of the military commander and royal regalia lying on the table beside him. Taking the king's instructions into consideration, Bacciarelli painted the portrait following the en gala pattern dating back to the time of the French absolute rulers, but in the more recent Rococo style. The king's pose was light, refined, elegant and graceful, which was in tune with the fashion of the day. The monarch noted down in his diary that the portrait caught the best likeness of him.
