Nivelon de Quierzy

[4] On 12 April 1204, Nivelon commandeered the Paradise, which led the naval attack against Constantinople and reached its harbour walls on the same day.

[4] After the crusaders took control of the city, Nivelon served as one of the twelve electors who installed Baldwin I as emperor of Constantinople.

[6] On 13 October 1205 or 1206, Nivelon returned to Soissons and delivered another batch of relics to his cathedral, including two pieces of the True Cross, one of Saint Blaise's ribs, the staff of Moses, and the skulls of Thomas the Apostle and John the Baptist.

[2][8] As a friend of Boniface I, Marquis of Montferrat, the commander of the crusade, Nivelon was appointed as archbishop of Thessalonica and was given special permission to remain as bishop of Soissons at the same time.

[9] Nivelon died on 13 September 1207 in Apulia,[4] having been sent back to the West to gather reinforcements for the Latin Empire in Greece.
