Pope Leo the Great
400 CE–461 CE · Rome
Leo the Great (c. 400–461) served as Bishop of Rome from 440 until his death, making him one of the most influential popes of antiquity. His Tome of Leo, a letter on the two natures of Christ, was formally endorsed at the Council of Chalcedon (451) and shaped orthodox Christology. He is traditionally credited with persuading Attila the Hun to withdraw from Italy in 452 through a personal embassy near the Mincio River. A skilled administrator and preacher, he asserted Roman primacy with exceptional force and was posthumously declared a Doctor of the Church.

The pope who rode out to meet Attila the Hun
In 452 CE, as Attila and his Huns pushed into northern Italy, Pope Leo the Great travelled north and met Attila near the river Mincio, by Mantua. Attila soon withdrew from Italy — ancient and later writers gave differing explanations for why. Three years later Leo led a similar embassy to the Vandal king during the sack of Rome.
How we know
Pope Leo I (bishop of Rome 440–461) met Attila near the Mincio in 452 CE; Attila then withdrew from Italy. Leo also interceded with the Vandal king Genseric during the sack of Rome in 455.

Rome in this era
Rome passed from weakened Western emperors into Ostrogothic hands under Theodoric (493) and then was bitterly contested during the Byzantine reconquest (535–554), yet its bishop — Pope Gregory the Great (590–604) — steered the church, organized missions, and preserved classical learning through the turmoil.
About Rome
Rome, on the Tiber in central Italy, grew from an Iron Age settlement into the capital of the Roman Republic and then of an empire that by the 1st century CE ruled the whole Mediterranean. Its Jewish community, attested from the 2nd century BCE, is among the oldest in Europe. Christian tradition holds that the apostles Peter and Paul died there, and the city became the seat of the popes. After the Western Empire ended in 476 it passed to Gothic kings, to Byzantium and then to papal rule as capital of the Papal States, until it became the capital of unified Italy in 1871. Vatican City, independent since 1929, lies within it.
