Pope Gregory X (Piacenza, c. 1210 – January 10, 1276 in Arezzo), born Theobald Visconti, was Pope from 1271 to 1276. Italian by birth, he spent most of his ecclesiastical career in the north, in the Low Countries. The Visconti Coat of Arms is the image of a large snake devouring a male child feet first. (Source: New Catholic Dictionary). He succeeded Pope Clement IV (1265–68) after the papal chair had been vacant for three years (1268–71) due to divisions among the cardinals; the equally split French and Italian cardinals wanted a Pope from their country due to the ongoing political situation with Charles of Anjou. The deadlock was finally broken when the citizens of Viterbo, where the cardinals were assembled, removed the roof from the building where the cardinals were meeting and locked them in, only allowing them bread and water; three days later, Pope Gregory X was elected. (Since then, the cardinals have always chosen the Pope under lock and key.) Gregory X was considered a strong choice because although he was Italian, he had spent most of his career north of the Alps and thus had not been embroiled in recent Italian political controversies.
His election came as a complete surprise to him, occurring while he was engaged in the Ninth Crusade to Acre with Edward I of England (1272–1307) in Palestine. Not wanting to leave his mission, his first action as Pope was to send out appeals for aid to the Crusaders, and at his final sermon at Acre just before leaving to sail for Italy he famously said "If I forget thee, O Jerusalem, let my right hand forget her cunning."
On his arrival at Rome his first act was to summon the council which met at the Second Council of Lyons in 1274 for the purpose of considering the East-West Schism, the condition of the Holy Land, and the abuses of the Catholic Church. It was while returning from that council that he died at Arezzo, where he is still buried inside the Cathedral Church, on January 10, 1276. To him is due the bull which, subsequently incorporated into the code of canon law, regulated all conclaves for papal elections until the reforms of Pope Paul VI (1963–78). He was succeeded by Pope Innocent V.
