In a surprise decision Thursday, Cardinal Robert Prevost was elected pope, taking the name Leo XIV and making history as the first American to lead the Catholic Church.
Pope Leo, appeared on the central balcony of St. Peter's Basilica around 70 minutes after white smoke billowed from a chimney atop the Sistine Chapel signifying the 133 cardinal electors had chosen a new leader for the 1.4 billion-member Catholic Church.
"Peace be with you all," the new pope told the cheering crowd.
The choice of Prevost was announced by French Cardinal Dominique Mamberti with the Latin words "Habemus Papam" (We have a pope) to tens of thousands of people gathered in St. Peter's Square to hear the news.
Aged 69 and originally from Chicago, Prevost has spent most of his career as a missionary in Peru and became a cardinal only in 2023. He has given a few media interviews and rarely speaks in public.
Leo becomes the 267th Catholic pope after the death last month of Pope Francis, who was the first Latin American pope and had led the Church for 12 years and widely sought to open the staid institution up to the modern world.
Francis enacted a range of reforms and allowed debate on divisive issues such as women's ordination and better inclusion of gender minority Catholics.
Ahead of the conclave, some cardinals called for continuity with Francis' vision of greater openness and reform, while others said they wanted to turn back the clock and embrace old traditions.
Prevost has attracted interest from his peers because of his quiet style and support for Francis, especially his commitment to social justice issues.
Prevost served as a bishop in Chiclayo, in northwestern Peru, from 2015 to 2023.
Francis brought him to Rome that year to head the Vatican office in charge of choosing which priests should serve as Catholic bishops across the globe, meaning he has had a hand in selecting many of the world's bishops.
Prevost said during a 2023 Vatican press conference: "Our work is to enlarge the tent and to let everyone know they are welcome inside the Church."
