Fiesco, Luigi

Fiesco, Luigi an Italian prelate, succeeded his uncle Giovanni through the favor of pope Urban VI, and was appointed, in 1385, cardinal-deacon, with the title of St. Adrian. Boniface IX nominated Luigi legate of the holy see in Romagna, and obtained by his instrumentality the submission of several cities, among them Anagni. In 1404 Luigi refused to recognise Cosmo de Migliorati (Innocent VII), who had been chosen by seven cardinals in place of Boniface IX. He put himself under the jurisdiction of the pope at Avignon, Pedro de Luna (Benedict XIII), whom lie abandoned in 1409 or 1410, to join Pietro Philargi (Alexander V). The successor of this latter pontiff, Baldassare Cossa (John XXIII), appointed Luigi governor of Bologna. In 1414 he attended at the Council of Constance, and in 1417 at the election of Ottone Colonna (Martin V). He was sent by this pontiff as a legate into Sicily, and returned to Rome, where he died, April 3, 1423. See Hoefer, Nouv. Biog. Generale, s.v.
