The Comtat Venaissin (; ; 'County of Venaissin'), often called the '''''' for short, was a part of the Papal States (1274–1791) in what is now the region of France. The entire region was an enclave within the Kingdom of France, comprising the area around the city of Avignon (itself always a separate ) roughly between the Rhône, the Durance and , and a small exclave located to the north around the town of bought by Pope John XXII. The also bordered (and mostly surrounded) the Principality of Orange. The region is still known informally as the , although this no longer has any political meaning.
In 1096, the Comtat was part of the Margraviate of Provence that was inherited by Raymond IV, Count of Toulouse from William Bertrand of Provence. These lands in the Holy Roman Empire belonged to Joan, Countess of Toulouse, and her husband, Alphonse, Count of Poitiers. Alphonse bequeathed it to the Holy See on his death in 1271. Since this happened during an interregnum, there was no Holy Roman Emperor to protect Joan's rights. The Comtat became a Papal territory in 1274. The region was named after its former capital, Venasque, which was replaced as capital by Carpentras in 1320. Map showing the Comtat and the Principality of Orange in 1547 Avignon was sold to the papacy by Joanna I, Queen of Naples and Countess of Provence, in 1348, whereupon the two comtats were joined together to form a unified papal enclave geographically, though retaining their separate political identities. The enclave's inhabitants did not pay taxes and were not subject to military service, making life in the Comtat considerably more attractive than under the French Crown. It became a haven for French Jews, who received better treatment under papal rule than in the rest of France. The Carpentras synagogue, built in the 14th century, is the oldest in France, and until the French Revolution preserved a distinctive Provençal Jewish tradition. Successive French rulers sought to annex the region to France. It was invaded by French troops in 1663, 1668 and 1768–1774 during disputes between the Crown and the Church. It was also subjected to trade and customs restrictions during the reigns of Louis XIV and Louis XV. Papal control continued until 1791, when an unauthorized plebiscite, under pressure from French revolutionaries, was held and the inhabitants voted for annexation by France. The process was facilitated by Pierre-Antoine Antonelle, then mayor of Arles. A few years later, Vaucluse département was created based on Comtat Venaissin including the exclave of Valréas and a part of the Luberon for the southern half. The papacy did not recognise this formally until 1814. Administration Under the Counts of Toulouse, the chief officer of the Comtat Venaissin was the Seneschal. From 1294 to 1791 the chief administrator of the Comtat Venaissin was the Rector, who was appointed directly by the Pope. Most of the incumbents were in fact prelates, either Archbishops or Bishops, and the Rector therefore had the right to wear a purple garb, similar to that of an Apostolic Chamberlain. His official residence was in Carpentras. He had no authority over Avignon, however, which was administered by a Cardinal Legate or a Vice-Legate, also appointed directly by the Pope. Gradually, however, the power of the Vice-Legate encroached on that of the Rector, until the Cardinal virtually held the position of a governor, and the Rector had the functions of a judge. In both cases their tenure was for a period of three years, renewable. The Rector had the right to receive the feudal oaths of homage of all the papal vassals. He also had the right to receive the oaths of bishops who held property by virtue of their office which was in feudal tenure from the pope. The Rector named the Notaries of the Comtat. He presided at the negotiation and payment of revenues of the Apostolic Chamber. His court was the Supreme Court of the Comtat Venaissin, and he had both criminal and civil jurisdiction of the first instance, and appellate jurisdiction from the courts of the regular judges of the three judicial circuits. The Rector was seconded by a Vice-Rector, named the Lieutenant of the Rector, also a papal appointee. He had judicial powers similar to those of the Rector. The administration of the Comtat was in the hands of the Estates of the Comtat, which consisted of the Élu (a nobleman), the Bishop of Carpentras, the Bishop of Cavaillon, the Bishop of Vaison, and eighteen representatives of the three judicial districts into which the Comtat was divided. The Estates held their meetings at Carpentras. The Apostolic Camera (Treasury of the Holy Roman Church) had a permanent office in Carpentras, with full jurisdiction in all financial matters concerning the rights of the Holy See in the Comtat. This included the obligations of bishops and other ecclesiastical persons to the papacy.
