Francesco Erizzo (Venice, February 18, 1566 – Venice, January 3, 1646) was the 98th Doge of Venice, reigning from his election on April 10, 1631 until his death fifteen years later. His reign is particularly notable because the last year of his reign saw the beginning of a war with the Ottoman Empire for control of Crete that would last for 24 years and dominate the geopolitics of the Mediterranean.
Francesco Erizzo was born into the Erizzo family, a patrician family from Istria. Although he was not particularly rich (in no small part because he had to cover for the debts of his brother), he nevertheless had a successful career in the service of Venice. He acted as Venetian ambassador to both Ferdinand II, Holy Roman Emperor and Pope Urban VIII. He also served as provveditore of various Venetian possessions. Erizzo never married.
Erizzo was elected as Doge of Venice on April 10, 1631, in the midst of the Italian plague of 1629–1631, which killed one third of the population of Venice, including Erizzo's predecessor Nicolò Contarini. He was elected by a vote of 40-1, although historian Claudio Rendina has pronounced this election fraudulent. (The only dissenting vote was cast for Renier Zen, the opponent of Giovanni I Cornaro known for his incorruptibility.)
In light of the bubonic plague then decimating the city (it would claim 45,000 victims in all), Erizzo's election was not accompanied by the customary festivities. The plague finally subsided in November 1631. Erizzo's predecessor, Nicolò Contarini, had taken a vow to build a church in honour of the Blessed Virgin Mary once the plague was over, which church was built and named Santa Maria della Salute. Erizzo now ordered that Venice would celebrate the Feast of the Presentation of Mary (November 21) as the Festa della Madonna della Salute, where the city's officials parade from San Marco to the Salute in the sestiere Dorsoduro for a service in gratitude for deliverance from the plague. This tradition is still observed in Venice to this day.
