 There were three main candidates, two of whom proved to be unacceptable to the Habsburgs, whose candidate, Alessandro Mattei, could not secure sufficient votes.However, Carlo Bellisomi also was a candidate, though not favoured by Austrian cardinals; a "virtual veto" was imposed against him in the name of Franz II and carried out by Cardinal Franziskus Herzan von Harras.After several months of stalemate, Jean-Sifrein Maury proposed Chiaramonti as a compromise candidate.
