Pope Nicholas V

Timeline

1. c. 1397–1444Sarzana; Bologna; Florence · LiguriaTommaso Parentucelli was born in Sarzana, Liguria, studied theology at the University of Bologna, and, due to poverty, served as tutor in the households of Rinaldo Albizzi and Cosimo de' Medici. He then became secretary and right-hand man to Bishop Albergati of Bologna, traveling across Europe on diplomatic missions and, with his patron's support, broadly collecting humanist documents and manuscripts, establishing a reputation for erudition early in life.
2. 1444–1447Bologna; Rome · Papal territoriesIn 1444 Parentucelli was appointed Bishop of Bologna by Pope Eugene IV, demonstrating outstanding administrative ability in handling Bologna's complex political situation. In 1446 he was raised to cardinal, and the following year, after Eugene IV's death, the college of cardinals elected him nearly unanimously as successor, testament to his wide prestige in the curia.
3. 1447–1452Vatican, Rome · Papal StatesAfter accession Nicholas V vigorously promoted Renaissance culture: he sponsored translations of Greek authors such as Thucydides, Strabo, and Polybius, commissioned scholars to organize the Vatican collections, laying the foundation of the Vatican Library. He generously funded building restorations, commissioned artists such as Fra Angelico to paint Vatican frescoes, and hired Alberti to oversee Rome's urban planning. In 1450 he proclaimed a Jubilee, attracting large numbers of pilgrims; in 1452 he crowned Frederick III in St. Peter's Basilica, the last Holy Roman Imperial coronation ever held in Rome.
4. 1453–1455Vatican, Rome · Papal StatesIn May 1453 Constantinople fell to the Ottoman forces; deeply shocked, Nicholas V issued a papal bull calling for a crusade, but few monarchs responded. His failing health did not allow him to see effective Christian unity; he died in Rome on March 24, 1455, leaving the papacy to his successor Callixtus III. His generous patronage of culture, art, and scholarship during his reign made him the founder of Renaissance papal policy.
