In 1624 he sent Richard Smith as vicar Apostolic to that country, but the latter's imprudent insistence on exercising full episcopal authority in England and Scotland brought him into public conflict with the Jesuits and other missionaries of religious orders.The Government issued new hostile measures against the Catholics, and in 1631 Smith was obliged to flee.He erected various dioceses and vicariates in pagan countries and encouraged the missionaries by word and financial assistance.
In 1592 Clement VIII made him Governor of Fano, then prothonotary Apostolic, and in 1601 papal legate to France to present his felicitations to King Henry IV on the birth of the dauphin, the future King Louis XIII.In 1604 he was appointed Archbishop of Nazareth and sent as nuncio to Paris, where he became very influential with Henry IV.Urban himself canonized Elizabeth of Portugal, 25 May, 1625; and Andrew Corsini, 22 April, 1629.He beatified : He reserved the beatification of saints to the Holy See and in a Bull, dated 30 October, 1625, forbade the representation with the halo of sanctity of persons not beatified or canonized, the placing of lamps, tablets, etc., before their sepulchres, and the printing of their alleged miracles or revelations. A book of poems, written by him before he became pope, was published during his pontificate under the title: "Maphei Cardinalis Barberini poemata" (Rome, 1637).The Jesuitesses, founded by the Englishwoman Mary Ward in 1609, he suppressed in 1631 for insubordination. Three days after his coronation he created Francesco Barberini, his nephew, cardinal ; in 1627 he made him librarian of the Vatican ; and in 1632 vice-chancellor. He built the large Barberini Palace and founded the famous Barberini Library which was acquired and made part of the Vatican Library by Leo XIII in 1902.
Urban's nephew, Antonio Barberini, the Younger, was created cardinal in 1627, became camerlengo in 1638, then commander-in-chief of the papal troops.He was legate at Avignon and Urbino in 1633; at Bologna, Ferrara, and Romagna in 1641.Urban's brother Antonio, who was a Capuchin, received the Diocese of Senigaglia in 1625, was created cardinal in 1628, and later appointed grand penitentiary and librarian of the Vatican.In a Bull, dated 22 April, 1639, he strictly prohibited slavery of any kind among the Indians of Paraguay, Brazil, and the entire West Indies.In his efforts to restore Catholicism in England Urban had little success.In recognition of his services in France, Paul Vcreated him cardinal-priest, 11 September, 1606, with the titular Church of S.
