Original prompt & settings (JSON) ↗A Roman pope was crowned in a German imperial city, in ceremonies split between a bishop's courtyard and the cathedral, with the King of the Romans present in regalia.
21 November 1417
Oddone Colonna, elected Pope Martin V ten days earlier, was ceremonially crowned at Constance on 21 November 1417. The ceremonies used both Constance Cathedral and the courtyard of the episcopal palace.
The cardinals conferred the papal coronation insignia in the presence of King Sigismund, prelates, princes, clergy, nobles and townspeople.
Three ordinations in three days
Colonna held no priestly or episcopal orders when the electors chose him. Jean Allarmet de Brogny, cardinal-bishop of Ostia, ordained him deacon on 12 November and priest on 13 November, then consecrated him bishop on 14 November.
Only after that sequence could the coronation proceed.
Where the official list begins
The Holy See's papal list dates Martin V's pontificate from 21 November 1417 and numbers him the 206th pope.
By the end of the ceremony he had been publicly inaugurated as the single pope around whom the major Western obediences could reunite. He stayed at Constance through the council's closing phase rather than going straight to Rome.
Benedict XIII never personally surrendered his claim, and retained a small following.
