The papal name "Leo" is chosen by popes to symbolize strength and bravery, as the name means "lion" in Latin. The name is historically significant, referring back to notable Popes like Leo I ("Leo the Great"), who is known for peacefully confronting Attila the Hun, and Leo III, who crowned Charlemagne as the first Holy Roman Emperor. Pope Leo XIV chose this name to honor the legacy of Pope Leo XIII, known for his intellectual contributions and social teachings, especially his efforts to engage the modern world and defend human dignity and labor rights amid changing times. By choosing the name Leo, Pope Leo XIV signals a commitment to continue the Church's intellectual mission, promote peace, justice, and uphold the dignity of the poor and vulnerable in continuity with the Church's tradition.

Pope Leo XIV is also notable for being the first American-born pope and the first naturalized Peruvian citizen pope, with a background in missionary work, social teaching, and a focus on dialogue and reconciliation between differing views within the Church and the modern world.

Thus, "why Pope Leo" reflects both a historical lineage of leadership and a contemporary commitment to addressing modern challenges in society and the Church.
