Editing Pope Urban IV (section)

==Early career==
Pantaléon was the son of a cobbler of [[Troyes]], [[France]].<ref name="Runciman54" /> He studied theology and [[common law]] in Paris and was appointed a canon of [[Laon]] and later [[Prince-Bishopric of Liège|Archdeacon of Liège]]. At the [[First Council of Lyon]] (1245), he attracted the attention of [[Pope Innocent IV]], who sent him twice on missions to [[Germany]].<ref name="Runciman54" /> In one of these missions, he negotiated the [[Treaty of Christburg]] between the pagan [[Old Prussians|Prussians]] and the [[Teutonic Knights]]. He became [[Bishop of Verdun]] in 1253. In 1255, [[Pope Alexander IV]] made him [[Latin Patriarch of Jerusalem]].<ref name="Runciman54" />

Pantaléon returned from Jerusalem, which was in dire straits,<ref name="Runciman54" /> and was at [[Viterbo]] seeking help for the oppressed Christians in the East when Alexander IV died. After a [[Sede Vacante|three-month vacancy]], the eight cardinals of the [[Sacred College]] chose him to succeed Alexander IV in a [[Papal election, 1261|papal election]] on 29 August 1261. He chose the regnal name of Urban IV, and was crowned in the church of [[Santa Maria a Gradi, Viterbo|Santa Maria a Gradi]] on September 4.<ref>[https://books.google.com/books?id=SdRaAAAAcAAJ Brevi Notizie della città di Viterbo e degli uomini illustri dalla medesima]; by Gaetano Coretini, Stamperia di San Michele a Ripa Grande, presso paolo Giunchi, (1774), page 59</ref>
