Pope Leo XIV made history on May 8, 2025, when he became the first pope born in the United States. Born Robert Francis Prevost in Chicago, Illinois, he spent decades serving the Catholic Church as a priest, missionary, bishop, and senior Vatican official before being elected to lead the world’s approximately 1.4 billion Catholics.
The 71-year-old pontiff is the 267th pope of the Roman Catholic Church and the first member of the Order of Saint Augustine to hold the position. His life story stretches from the suburbs of Chicago to missionary communities in Peru and eventually to Vatican City. Unlike many church leaders whose careers developed primarily in Rome, Leo XIV brings extensive experience working with communities in Latin America, alongside years of international church administration.
Early Life and Family Background
Robert Francis Prevost was born on September 14, 1955, in Chicago, Illinois, to Louis Marius Prevost and Mildred Agnes Martínez. He grew up in Dolton, a suburb south of Chicago, alongside his two brothers, Louis Martín and John Joseph.
His father served in the United States Navy during World War II before working in education as a teacher and school principal. His mother worked as a school librarian and was actively involved in parish life.
Religion was an important part of the Prevost household. Both parents participated in church activities, and their children grew up surrounded by Catholic traditions.
From an early age, Robert showed an interest in religious life. He attended Saint Mary of the Assumption School before enrolling at Saint Augustine Seminary High School in Holland, Michigan.
His school years also included interests beyond religion. He participated in student leadership, enjoyed tennis, and developed the academic discipline that later supported his theological studies.
Pope Leo XIV’s Education and Priesthood
After completing high school, Prevost attended Villanova University in Pennsylvania.
He graduated in 1977 with a mathematics degree and also studied philosophy. His educational background was somewhat unusual for a future pope, combining scientific reasoning with an interest in religious questions.
Later that year, he entered the novitiate of the Order of Saint Augustine in Saint Louis, Missouri.
He made his first religious profession in 1978 and took his solemn vows in August 1981.
Prevost continued his theological education at the Catholic Theological Union in Chicago before traveling to Rome to study canon law.
On June 19, 1982, he was ordained a Catholic priest.
He later earned a doctorate in canon law from the Pontifical University of Saint Thomas Aquinas. His research examined leadership and governance within the Augustinian Order.
These academic experiences prepared him for responsibilities involving church administration, religious education, and pastoral leadership.
His Missionary Work in Peru
One of the most important chapters in Pope Leo XIV’s biography began in 1985, when he traveled to Peru as an Augustinian missionary.
His early assignment took him to Chulucanas, where he became familiar with the challenges facing local Catholic communities.
He later worked extensively in Trujillo, serving in religious formation, parish ministry, and education.
His responsibilities included teaching canon law, helping prepare future priests, and supporting communities with limited resources.
Life in Peru was very different from the academic environment he had experienced in the United States and Rome.
He worked closely with local families and church leaders, gaining an understanding of social inequality and the everyday difficulties experienced by poorer communities.
These experiences helped shape his pastoral outlook.
His long association with Peru also became a defining part of his identity. He eventually obtained Peruvian citizenship in August 2015, making him a dual citizen of the United States and Peru.
From Augustinian Leader to Bishop of Chiclayo
Prevost’s leadership abilities became increasingly visible during his years with the Augustinian Order.
In 2001, he was elected Prior General, becoming responsible for overseeing Augustinian communities across the world.
He held the position for two consecutive six-year terms, remaining in office until 2013.
The role required international travel, administrative decision-making, and communication with religious communities from different cultural backgrounds.
After completing his tenure, he returned to the United States.
However, his work in Peru was far from finished.
In November 2014, Pope Francis appointed him Apostolic Administrator of the Diocese of Chiclayo.
He was ordained a bishop in December 2014 and formally became Bishop of Chiclayo in September 2015.
During his years in the diocese, he became known for his pastoral approach and involvement in church administration.
His experience in Peru later became particularly significant when he was considered for senior leadership responsibilities in Rome.
How Robert Prevost Became a Cardinal
In January 2023, Pope Francis appointed Robert Prevost Prefect of the Dicastery for Bishops.
The position is one of the Vatican’s most influential administrative roles because the office helps oversee the selection of bishops in many parts of the world.
Prevost was also appointed President of the Pontifical Commission for Latin America.
These responsibilities placed him at the center of important discussions about church leadership and international Catholic communities.
In September 2023, Pope Francis elevated him to the College of Cardinals.
His appointment recognized decades of service involving missionary work, religious leadership, and church governance.
As a cardinal, Prevost became eligible to participate in a future papal conclave.
His international experience and familiarity with both North American and Latin American Catholic communities made him a distinctive figure within the Vatican.
Pope Leo XIV’s Historic Election
Following the death of Pope Francis in April 2025, cardinals gathered in Vatican City to elect his successor.
The conclave began on May 7, 2025.
One day later, Robert Francis Prevost was elected pope.
He chose the name Leo XIV and became the first American-born pontiff in Catholic Church history.
His election also marked the first time a member of the Augustinian Order had become pope.
When he appeared on the balcony of Saint Peter’s Basilica, his first message emphasized peace.
His selection represented an important moment for Catholics in the United States, Peru, and the wider international Church.
His formal inauguration took place on May 18, 2025.
Why He Chose the Name Leo XIV
The choice of Leo XIV carries historical and religious significance.
The name honors the legacy of Pope Leo XIII, who led the Catholic Church from 1878 to 1903.
Leo XIII is especially remembered for his 1891 encyclical Rerum novarum, which addressed workers’ rights, social justice, and the responsibilities of employers and governments.
By selecting the name Leo, the new pontiff signaled an interest in applying Catholic social teaching to contemporary challenges.
His episcopal motto, In Illo Uno Unum, expresses the idea of unity in Christ.
The phrase reflects his Augustinian background and his emphasis on building connections across different cultures and communities.
His early public messages have frequently highlighted peace, dialogue, and human dignity.
Pope Leo XIV’s Teachings on Artificial Intelligence
Pope Leo XIV has placed particular attention on the ethical questions created by technological development.
In May 2026, he published his first encyclical, Magnifica humanitas, addressing the protection of human dignity in the age of artificial intelligence.
The document examines the growing influence of AI on employment, social relationships, and human decision-making.
It emphasizes that technological progress should serve people rather than reduce individuals to economic or technological resources.
The encyclical also reflects his broader concern for workers and vulnerable communities.
By connecting modern technology with traditional Catholic social teaching, Leo XIV has sought to address questions that extend well beyond religious institutions.
His approach highlights the need for responsible innovation, ethical leadership, and respect for human dignity.
Pope Leo XIV’s Health and Latest Updates
Pope Leo XIV remains active in his role as head of the Catholic Church, although a recent health announcement has attracted international attention.
On October 11, 2026, the 71-year-old pontiff announced that doctors had discovered a small, localized nodule in his lung during a medical examination.
He said he would undergo surgery at Rome’s Gemelli Hospital to remove the growth.
The Vatican indicated that his recovery was expected to take approximately one week.
The nature of the nodule has not been publicly established, and there has been no confirmed diagnosis of cancer.
Despite the planned procedure, the pope has continued carrying out his responsibilities and is preparing for a pastoral visit to Latin America in November, including stops in Uruguay, Argentina, and Peru.
The announcement has brought renewed attention to his health, but no major change to his longer-term leadership responsibilities has been confirmed.
