The House of Barberini are a family of the Italian nobility that rose to prominence in 17th century Rome. Their influence peaked with the election of Cardinal Maffeo Barberini to the papal throne in 1623, as Pope Urban VIII. Their urban palace, the Palazzo Barberini, completed in 1633 by Bernini, today houses Italy's Galleria Nazionale d'Arte Antica (National Gallery of Ancient Art). Early history The Barberini family were originally a family of minor nobility from the Tuscan town of Barberino Val d'Elsa, who settled in Florence during the early part of the 11th century. Carlo Barberini (1488–1566) and his brother Antonio Barberini (1494–1559) were successful Florentine grain, wool and textile merchants. In 1530 Antonio participated in the defense of the Florentine Republic but after the capture of the city by Imperial troops, and the return to power of the Medici, Antonio grew weary of Medici rule and left Florence in 1537 to oversee Barberini business in Rome. In 1552, Carlo's son Francesco followed his uncle to Rome and business flourished. Francesco became a very rich man and bought a number of high offices within government and the Catholic church. In 1559, his uncle Antonio was murdered by forces loyal to the Medici. Francesco continued to build his fortune and amass titles until his death in 1600. Ordinarily his estate would have been "fined" by the Camera Apostolica for operating a business while holding church office but his relatives successfully appealed to the head of the organization Francesco had, himself, once directed. The continuation of Barberini business fell to his nephews (the sons of his brother, also Antonio Barberini, who had died in 1571) including Maffeo Barberini. Maffeo Barberini as Pope Urban VIII The Barberini acquired great wealth and influence when Cardinal Maffeo Barberini was elected to the papal throne in 1623, taking the name Pope Urban VIII. He elevated a brother Antonio Marcello Barberini (Antonio the Elder) and two nephews, Francesco Barberini and Antonio Barberini, to the cardinalate. He made another brother Duke of Monterotondo, and gave a third nephew, Taddeo Barberini, the principality of Palestrina. Taddeo was also made Gonfalonier of the Church, Prefect of Rome and Commander of Sant'Angelo. The ecclesiastical, diplomatic and cultural accomplishments of Urban's reign were overshadowed by the nepotism the pope practised. Urban's contemporary, John Bargrave, wrote: Likewise, the War of Castro, toward the end of Urban's papacy, sullied Urban's reputation and the popularity
