Pope St. Zachary was the 91st pope of the Catholic Church, serving from 741 until his death in 752. Known for his diplomacy, kindness, and efforts to maintain peace during a politically unstable time, he helped stabilize the Church’s influence in both Rome and Europe.
St. Zachary was born in 679 in San Severino, Calabria, in the Byzantine Empire (modern-day southern Italy), of Greek descent. He was well-educated and fluent in both Greek and Latin, which would later aid his pontificate as he navigated the complicated relationship between the Roman Church and both Eastern and Western powers.
He was elected pope in 741, succeeding Pope Gregory III during a critical period of Church and European history. As Pope, Zachary took on not only spiritual duties but also major political challenges. The Lombards, a Germanic people who had invaded and settled much of Italy, were threatening the Papal States. Zachary negotiated peace with Lombard King Liutprand, using his wisdom and diplomacy rather than force—resulting in the return of Church lands and protection of Christians in Lombard territory.
One of his most important political acts was supporting Pepin the Short's claim to the Frankish throne, ultimately laying the foundation for the Carolingian dynasty and the future reign of Charlemagne. This alliance between the papacy and the Franks would become pivotal for centuries of European history.
St. Zachary also worked hard to improve the moral and spiritual integrity of the Church. He condemned simony (the buying and selling of Church offices), fought heresy, and worked for the protection of monastic communities. He was also known for caring for the poor and for rebuilding and restoring churches in Rome.
He passed away peacefully on March 15, 752, after eleven years as pope. He was buried in St. Peter’s Basilica, and was immediately venerated by the faithful for his holiness, intelligence, and dedication to peace.
