The pope is called Leo because the newly elected pontiff chose “Leo XIV” as his papal name, drawing on a long line of earlier popes named Leo and on the symbolism of the word itself.

What “Leo” means

  • “Leo” comes from Latin and means “lion,” a symbol of strength, courage, and leadership.
  • The name is meant to suggest a pope who can lead the Church firmly through turbulent times, including political tensions and rapid technological change.

Historical Leos and why that matters

  • There have been 13 previous popes named Leo, making it one of the most common papal names in history.
  • The most famous is Leo the Great (5th century), remembered for confronting Attila the Hun and for major theological contributions; invoking his name hints at doctrinal clarity and moral courage.
  • Leo XIII (late 19th century) is known for the encyclical Rerum Novarum on workers’ rights and social questions; choosing “Leo” connects the new pope to that social-justice legacy in a 21st‑century context.

Why this pope picked “Leo XIV” now

  • The current pope, formerly Cardinal Robert Prevost, became Pope Leo XIV in May 2025 and appears to be signaling continuity with Pope Francis on issues like social justice, care for the poor, and a “synodal” Church.
  • Commentators note that the name suggests a leader willing to “stand up to oppressive political forces in the world” and to address new challenges such as artificial intelligence, echoing Leo XIII’s response to industrialization.

How papal names work in general

  • New popes are free to choose a name, often to honor a saint or predecessor or to signal the tone and priorities of their papacy.
  • About half of all popes in history have changed their birth name on election; names like John, Gregory, Benedict, Pius—and now Leo—carry strong historical and symbolic weight.

In short, he’s called “Leo” because he intentionally chose a name that means “lion,” evokes powerful past popes, and signals a mission of strength, social concern, and doctrinal clarity for today’s Church.
