Pope Gregory X, born in the year twelve ten, served as the head of the Catholic Church and the ruler of the Papal States from the first of September, twelve seventy-one until his death. A member of the Third Order of St. Francis, his papacy was marked by significant events and reforms.
His election followed an extensive conclave that lasted from twelve sixty-eight to twelve seventy-one, making it the longest papal election in history. During his tenure, Gregory convened the Second Council of Lyon, which aimed to address various issues within the Church and its governance.
In addition to his ecclesiastical duties, Gregory X implemented new regulations regarding the papal conclave, which, despite being briefly annulled by subsequent popes, remained the standard practice for centuries. His rules provided a framework for the election of future popes, allowing for flexibility in extraordinary circumstances.
Gregory's legacy continued long after his death, as he was beatified by Pope Clement XI in seventeen thirteen, following the confirmation of his cultus. His contributions to the Church and the papal election process have had a lasting impact on the governance of the Catholic Church.
