Gregory X, Pope
Reigned from 1 September 1271 to 20 January 1276 . Born in 1210 in Piacenza, Italy as Teobaldo Visconti; died on 20 January 1276 at Arezzo, Italy . After the death of Pope Clement IV in 1268, the Holy See was vacant for nearly three years. Finally the archdeacon of Liege, though not yet a priest, was elected in 1271. He was ordained and consecrated in 1272. The outstanding event of his reign was the convocation of the Council of Lyons, in which he effected a temporary union with the Greeks, sought to restore peace between the Guelphs and Ghibellines in Tuscany and Lombardy, and made plans for a crusade to lighten the oppression of Christians in Palestine. He crowned Rudolf of Hapsburg as emperor. Because of his great virtue, he is revered as a saint in Rome and in a number of Italian dioceses.

Gregory X, Pope
previously known as TEBALDO DE’ VISCONTI, was born at Piacenza, of the illustrious family of Visconti. He was chosen pope while absent with the prince of Wales in the Holy Land. The see had been vacant nearly three years after the death of Clement IV. Gregory greatly encouraged the Crusades. In 1271 he summoned the Council of Lyons, which convened in 1274. See LYONS. He died at Arezzo, Jan. 19, 1276. This pope instituted the regulations of the conclave nearly as they exist at the present time. There are twenty-five epistles of Gregory in Labbe, ConciI. vol. xi. Gerard Vossius published his Vita et Epistolae (Grk. and Lat. Rome, 1587) See Bower, Hist. of Popes, vol. viii; Bonacci, Pontif Gregorio X (Rome, 1711, 4to).
