On May 8, 2025, white smoke billowed from the chimney on the roof of the Sistine Chapel, signaling that a new pope had been chosen. On that day, the world was introduced to Pope Leo XIV, known just hours before as Cardinal Robert Prevost, prefect of the Vatican’s Dicastery for Bishops.
One year later, Pope Leo has captured the hearts of the faithful through his papal trips, events like canonizations and special liturgies, as well as through his spoken and printed words, including an apostolic letter, and much more.
Here are 10 of the most significant events and moments of Leo XIV’s first year as pope:
The new pontiffʼs inaugural Mass
On May 18, 2025, Pope Leo XIV inaugurated his pontificate with a Mass in St. Peter’s Square calling for a united Church. Addressing approximately 150,000 attendees, he emphasized fraternal communion, servant leadership, and reconciliation, marking the official start of his ministry as the 266th successor of St. Peter.
At the Mass, concelebrated with the members of the College of Cardinals, Leo expressed his intention to “come to you as a brother, who desires to be the servant of your faith and your joy, walking with you on the path of God’s love, for he wants us all to be united in one family.”
Visit to Pope Francis’ tomb
Less than 48 hours after his election, Pope Leo made his first visit outside of the Vatican visiting the Shrine of the Mother of Good Counsel in Genazzano, located about an hour east of Rome and run by the religious of the Order of St. Augustine.
On his way back to the Vatican, the new pontiff stopped at the Basilica of St. Mary Major where he prayed before the tomb of Pope Francis and the icon of the Blessed Virgin Mary there, “Salus Populi Romani.”
Pope Leo left a white rose, which is said to have been Pope Francis’ favorite flower.
Impactful addresses to youth
Throughout his first year as pope, the Holy Father has had powerful experiences with young people. Two in particular that stand out are his addresses to roughly 1 million young adults during the Jubilee of Youth and his live talk with young people gathered at the National Catholic Youth Conference (NCYC).
During the Jubilee of Youth, which took place July 28–Aug. 3 and was part of the yearlong Jubilee of Hope, young adults from around the world filled the streets of Rome. Each day was filled with different opportunities and events for the young people to experience the richness of the Catholic faith.
On Aug. 2, Pope Leo was greeted by the largest crowd he had addressed during his pontificate so far for the evening vigil at Tor Vergata, an outdoor venue 10 miles east of Rome. An estimated 1 million people were in attendance. The Holy Father arrived by helicopter and then drove through the grounds on the popemobile, waving to the cheering young people before the prayer service began.
The Jubilee of Youth concluded on Aug. 3 with a Mass celebrated by Pope Leo on the 237-acre grounds of Tor Vergata, where more than a million young pilgrims had spent the night following a prayer vigil and Eucharistic adoration.
In his homily, Pope Leo invited the pilgrims to open their hearts to God and venture with him “towards eternity.”
NCYC took place in Indianapolis at Lucas Oil Stadium from Nov. 20–22. On Nov. 21, Pope Leo held a historic digital encounter with American teenagers.
During this live conversation, five teenagers asked the pope questions regarding using technology, recovering from mistakes, giving worries to Jesus, avoiding distractions, and preparing for the future of the Church. The pope gave guidance to the young crowd with words applicable to both teenagers and the universal Church.
