Malatesta Ungaro
Malatesta Ungaro (June 1327 – 17 July 1372) was born Galeotto Malatesta, a younger son of Malatesta Guastafamiglia, lord of Pesaro and Rimini, and Costanza Ondedei. He took the name Ungaro after King Louis I of Hungary knighted him in December 1347. He married Costanza d'Este, daughter of Obizzo III of Ferrara, in 1363.
As a papal commander under Cardinal Gil de Albornoz he fought the Ordelaffi and Manfredi, and on 16 April 1363 he heavily defeated Bernabò Visconti. He helped Pope Urban V return to Rome in 1367 and died at Rimini in 1372.
