A Dominican, and the Order's former Master General (1296–1298),[4] Niccolò Boccasini was unanimously elected Pope Benedict XI on the first scrutiny.

[5] Niccolò Boccasini and Pedro Rodriguez were the only cardinals, of the seventeen or eighteen, who had stayed with Boniface VIII at Anagni when the papal residence was invaded by the French and the Colonna, and the Pope seized and imprisoned.

[5] Benedict XI was crowned at the Vatican Basilica on Sunday, 27 October 1303 by Cardinal Matteo Rosso Orsini, the prior Diaconorum.

[5] Pope Benedict left a detailed account of the conclave that elected him, describing how it closely adhered to the procedures mandated in the papal bull Ubi periculum.

[6] Two other cardinals, Giacomo and Pietro Colonna (uncle and nephew), had been deposed by Pope Boniface VIII and were thus ineligible to participate in the election.
