In the papal conclave held from 14 to 16 June 1846, Giovanni Maria Mastai Ferretti, Bishop of Imola, was elected on the fourth ballot to succeed the recently deceased Gregory XVI as pope. He took the name Pius IX. Of the 62 members of the College of Cardinals, 52 assembled in the Quirinal Palace, one of the papal palaces in Rome and the seat of two earlier 19th century conclaves. The conclave was the last to elect a ruler of the Papal States, the extensive lands around Rome and Northern Italy which the Catholic Church governed until 1870.
The papal conclave held from 18 to 20 February 1878 saw the election of Vincenzo Pecci, who took the name Leo XIII as pope. Held after the death of Pius IX, who had had the longest pontificate since Saint Peter, it was the first election of a pope who would not rule the Papal States. It was the first to meet in the Apostolic Palace in the Vatican because the venue used earlier in the 19th century, the Quirinal Palace, was now the palace of the king of Italy, Umberto I.
The papal conclave that followed the death of Pius VI on 29 August 1799 lasted from 30 November 1799 to 14 March 1800 and led to the selection of Cardinal Barnaba Chiaramonti, who took the name Pius VII. This conclave was held in Venice and was the last to take place outside Rome. This period was marked by uncertainty for the papacy and the Roman Catholic Church following the invasion of the Papal States and abduction of Pius VI under the French Directory.

Jus exclusivae was the right claimed by several Catholic monarchs of Europe to veto a candidate for the papacy.

Giuseppe (Andrea) Albani was an Italian Roman Catholic Cardinal. He played an important role in the elections of Leo XII, Pius VIII and Gregory XVI.
A cardinal-nephew was a cardinal elevated by a pope who was that cardinal's relative. The practice of creating cardinal-nephews originated in the Middle Ages, and reached its apex during the 16th and 17th centuries. The last cardinal-nephew was named in 1689 and the practice was abolished in 1692. The word nepotism originally referred specifically to this practice, when it appeared in the English language about 1669. From the middle of the Avignon Papacy (1309–1377) until Pope Innocent XII's anti-nepotism bull, Romanum decet pontificem (1692), a pope without a cardinal-nephew was the exception to the rule. Every Renaissance pope who created cardinals appointed a relative to the College of Cardinals, and the nephew was the most common choice, although one of Alexander VI's creations was his own son.

The 1689 papal conclave was convened after the death of Pope Innocent XI. It led to the election of Cardinal Pietro Vito Ottoboni as Pope Alexander VIII. The conclave saw previous factions join together because they lacked numerical strength, and saw the rise of the zelanti as a political force in the election of the next pope. Ottoboni was eventually unanimously elected with the consent of the secular monarchs, becoming the first Venetian in over 200 years to be elected pope.
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.
Pope Pius VII created 99 cardinals in 19 consistories.
Carlo Oppizzoni, spelled also Opizzoni or Oppizoni, was a Roman Catholic cardinal and archbishop.
