Pope Gregory X

Pope Gregory X, who reigned from 1271 to 1276, is best known for his role in reforming the Catholic Church and promoting church unity. He convened the Second Council of Lyon in 1274, which aimed to address issues like the unification of the Eastern and Western Churches after centuries of division. Gregory X also emphasized the importance of a papal election process, which led to the establishment of the conclave system to elect popes in a more orderly and less politically influenced manner. His efforts laid groundwork for future reforms in the Church’s governance.
