Apostolic Palace, Papal States
Name taken: Innocent XII
The 1691 papal conclave was convened on the death of Pope Alexander VIII and ended with the election of Cardinal Antonio Pignatelli as Pope Innocent XII. It lasted for five months, from 12 February to 12 July 1691. The conclave became deadlocked after Catholic monarchs opposed the election of Gregorio Barbarigo, who some members of the College of Cardinals also viewed as too strict. The conclave only ended in July when cardinals started to become ill from the heat, and after French cardinals agreed to vote for Pignatelli despite him coming from Spanish-controlled Naples.
Alexander was also noted for his nepotism that was partially due to his advanced age and belief that his family would have little time to profit from his reign. This was in contrast to his predecessor
The conclave began on 12 February 1691, and membership in the College of Cardinals was at its statutory maximum of 70 cardinals. Despite this, at the beginning of the conclave only 38 electors were present. The number rose to 44 electors present by 19 February 1691, and by the time of the election of Innocent XII in July, 61 electors were present.
The curial cardinals entered the conclave seeking to elect
Despite Leopold not formally excluding Barbarigo, a rumour spread that he had been excluded, and despite the protests of the zelanti faction of cardinals, enough members of the College of Cardinals recognized the Emperor's ability to exclude a candidate that it prevented his election. Leopold had sent an envoy with two letters for his cardinals: the first public letter declared that he did not wish to see Barbarigo excluded, while the second letter, which was private, expressed his desire that Barbarigo not be elected, but that he did not want to take the blame for the exclusion, but rather wished for the Spanish to be the ones to do so. Additionally, some of the more materialistic cardinals feared that Barbarigo would be similarly strict as Pope Innocent XI, and this factored into his failure to win election.
It was clear to the cardinals that Barbarigo would not be elected pope by the end of April, and the conclave entered a period where it had no clear direction. The daily scrutinies would return no successful candidates, and the afternoon scrutinies would often simply repeat the deadlock that had occurred in the morning. Votes even went to non-cardinals for the first time in a conclave since 1503. There was no clear lead as to who might be elected pope, and at one point several cardinals started a fire in the living quarters by accidentally knocking over a lamp while playing cards. While this caused some of the cells housing the cardinals to be unlivable, three cardinals had died by that point so there was room available to relocate the cardinals who had been put out of their previous housing.
Election of Innocent XII
Federico Altieri began seeking to secure election to the papacy for himself. He had sought to both have a public persona favourable to Leopold I, while also working to curry the favour of Louis XIV. The zelanti faction and Flavio Chigi opposed him, which was enough to stop his victory.
Altieri had positioned himself with his campaign as a credible faction leader within the conclave, and began working to elect his friend Antonio Pignatelli pope. Altieri worked to convince the French cardinals that Pignatelli would not work for the Spanish as pope even though he was from
