Urbano IV

Pope Urban IV, born Jacques Pantaléon, served as pope from 1261 to 1264. He is best known for instituting the Feast of Corpus Christi, which celebrates the real presence of Christ in the Eucharist. This feast was established following his experiences and the miraculous events reported by a nun in Bolsena, Italy. Urban IV's papacy was marked by efforts to reform the church and strengthen its authority, as well as his interest in the theological implications of the Eucharist, which deeply influenced Catholic liturgical practices.
