Saint Leander of Seville was a prominent bishop in the early Christian Church, serving as the Archbishop of Seville in the 6th century. He played a crucial role in the conversion of the Visigoths from Arianism to Catholicism, helping to unify the Christian faith in Spain. His efforts contributed to the establishment of a strong Christian community in the region. Leander was born around 534 in Carthage and later became known for his theological writings and pastoral care. He is often associated with his brother, Saint Isidore of Seville, who succeeded him as archbishop. Saint Leander is commemorated on March 13 in the Catholic Church.
