the Palazzo Chigi. The Palazzo Chigi in Rome is not to be confused with the Palazzo Chigi in S. Quirico d'Orcia in Tuscany, or the Palazzo Chigi di Formello. Foreign relations Malta Before being elected as Pontiff, Chigi served as Inquisitor on the Island of Malta where he resided mostly at the Inquisitor's Palace in Birgu (alias Città Vittoriosa). At that time Malta was a fiefdom of the Knights Hospitallers of the Sovereign Order of Saint John of Jerusalem, Knights of Malta, from which he purchased one hundred slaves in 1662 for his naval squadron. Sweden The conversion of Queen Christina of Sweden (1632–1654) occurred during Alexander VII's reign. After her abdication the queen came to reside in Rome, where she was confirmed in her baptism by the Pope, in whom she found a generous friend and benefactor, on Christmas Day, 1655.

While the pontiff had originally hoped that Christina would become an inspiration for those considering conversion to the faith, he was dismayed that her interests were primarily political, even to the point that she helped plot the conquest of Naples with Cardinal Jules Mazarin. France In foreign policy his instincts were not as humanist or as successful.

During the conclave, he had been hostile to Chigi's election, but was in the end compelled to accept him as a compromise. However, he prevented Louis XIV from sending the usual embassy of obedience to Alexander VII, and, while he lived, he foiled the appointment of a French ambassador to Rome, diplomatic affairs being meantime conducted by cardinal
