Charles Borromeo (Italian: Carlo Borromeo; Latin: Carolus Borromeus; 2 October 1538 – 3 November 1584) was the Archbishop of Milan from 1564 to 1584 and a cardinal of the Catholic Church. He was a leading figure of the Counter-Reformation combat against the Protestant Reformation together with Ignatius of Loyola and Philip Neri. In that role he was responsible for significant reforms in the Catholic Church, including the founding of seminaries for the education of priests. He is honoured as a saint by the Catholic Church, with a feast day on 4 November.
