Pope Leo XIV: Biography of the First American Pope

When white smoke billowed from the Sistine Chapel on May 8, 2025, the world met a pope unlike any before him. Robert Francis Prevost, a Chicago-born Augustinian who spent decades as a missionary in Peru, took the name Leo XIV – becoming the first pope ever from the United States.

Birth name: Robert Francis Prevost ·

Place of birth: Chicago, Illinois, USA ·
Religious order: Order of Saint Augustine (Augustinians) ·
Elected pope: 8 May 2025 ·
Papal name: Leo XIV

Nine key facts, one pattern: a life divided between the United States, Peru, and the Vatican.

The table below summarizes his formal biographical data.

What is Pope Leo XIV known for?

First pope born in the United States

• He was born in Chicago, Illinois, in 1955. (Britannica – encyclopedia entry)

No American had ever ascended to the papacy before. Leo XIV’s election on 8 May 2025 broke that historical barrier. The Vatican’s official biography states he “is the first Pope from the United States of America.”

First pope from the Order of Saint Augustine

• He is the first Augustinian pope in Church history. (Vatican – official biography)

The Order of Saint Augustine, founded in 1244, had never produced a pope until Leo XIV. His formation as an Augustinian friar – emphasizing community, poverty, and missionary work – is expected to influence his pontificate.

First pope to hold Peruvian citizenship

• He acquired Peruvian citizenship in 2015 during his missionary and episcopal service. (Wikipedia – community-reviewed encyclopedia)

This dual citizenship reflects his deep ties to Peru, where he lived and worked for over a decade. The U.S. Conference of Catholic Bishops notes that he “spent many years as a missionary in Peru” before returning to leadership roles in the United States.

The implication: Leo XIV’s papacy will be shaped by a uniquely American, Peruvian, and Augustinian perspective.

What is Pope Leo XIV’s background?

Early life and education

• Born Robert Francis Prevost on 14 September 1955 in Chicago. (Catholic Standard – diocesan publication)
• Studied at Villanova University, an Augustinian institution. (Villanova University – Augustinian university press release)
• Entered the Augustinian order and was ordained a priest in 1982. (Vatican – official biography)

Prevost grew up in a Catholic family on Chicago’s northwest side. He attended Villanova, a university run by the Augustinians, and after graduation pursued a vocation with the same order. He studied theology in Rome and was ordained a priest on 19 June 1982 by Archbishop Jean Jadot.

Priesthood and missionary work in Peru

• He served as a missionary in Peru from 1985 to 1998. (Vatican News – Holy See news service)
• He was a parish pastor and later director of the Augustinian seminary in Peru. (Georgetown University – academic analysis)
• He returned to the United States to serve as prior general of the Augustinians for two terms. (Vatican News – Holy See news service)

Those thirteen years in Peru deepened his connection to the country and its people. He learned Spanish, became a naturalized citizen, and took on pastoral responsibilities that ranged from running a parish to training future priests. His leadership of the Augustinian order from 2001 to 2013 gave him a global perspective on the Church.

Episcopal appointments and cardinalate

• Appointed Bishop of Chiclayo, Peru in 2014. (Vatican – official biography)
• Promoted to Archbishop of Lima in 2023. (Vatican – official biography)
• Created a cardinal by Pope Francis in 2024. (Vatican – official biography)

His rise through the hierarchy was swift. As Archbishop of Lima, he led the oldest diocese in the Americas. Pope Francis, whose own background is Latin American, elevated him to cardinal in 2024, making him a key figure in the College of Cardinals. The U.S. Conference of Catholic Bishops noted that before the conclave, Prevost was the American cardinal most often mentioned as a potential successor to Saint Peter.

What is Pope Leo XIV’s nationality?

American citizenship

• He was born in the United States and retains U.S. citizenship. (Britannica – encyclopedia entry)

His birth in Chicago makes him a natural-born U.S. citizen. The USCCB’s announcement described him as a “Chicago native” and emphasized his American roots.

Peruvian citizenship

• He acquired Peruvian citizenship in 2015 after years of missionary work and service as a bishop. (Wikipedia – community-reviewed encyclopedia)

Peru granted him citizenship by naturalization, a reflection of his long-term commitment to the country. He is the first pope to hold Peruvian nationality, and his dual citizenship symbolizes the bridge between North and South America that his papacy represents.

The trade-off: while his American citizenship resonates with U.S. Catholics, his Peruvian identity gives him credibility with the Global South, where the majority of the world’s Catholics now live.

For American Catholics, Leo XIV’s election is a moment of both pride and expectation: their first fellow citizen on the papal throne, but one whose formation happened far from the US, in Peru and the Augustinian tradition. The choice is clear: embrace a pope who carries the hopes of the Americas, or watch him steer the Church in directions that may surprise even his home country.
