The House of Malatesta was an Italian family that ruled over Rimini from 1295 until 1500, as well as (in different periods) other lands and towns in Romagna and holding high positions in the government of cities in present day Tuscany, Lombardy and Marche. The dynasty is considered among the most important and influential of the Late Middle Ages. In the period of maximum influence, they extended their domains along the Marche coast, up to Ascoli Piceno, Senigallia, Sansepolcro and Citerna, and to the north, on the territories of Bergamo and Brescia. History The family's progenitor is said to be Rodolfo of Carpegna whose fighting spirit yielded him the sobriquet mala testa ("bad head"). From 1004 on he built a castle on the rock of Pennabilli. In the 11th century the family had possessions in the region of Gabicce Mare, Gatteo and Poggio Berni. Giovanni Malatesta (d. 1150) owned some land between rivers Marecchia and Rubicon, and was the first to settle down in Rimini. His son married into the Traversari family who were lords of Ravenna and Rimini during the 12th and 13th centuries. In 1186 the Malatesta became lords of Torriana. Giovanni's grandsons Giovanni and Malatesta I Malatesta (1183–1248) founded the branches of the Counts of Sogliano al Rubicone (extinguished in 1640) and "della Penna" of Pennabilli and Verucchio (until 1462). In 1216 they became citizens of Rimini. Malatesta I became podestà (chief magistrate) of Pistoia in 1228 and of Rimini in 1239 and 1247. During the struggles between papal and imperial followers (Guelphs and Ghibellines), he supported emperor Frederick II. His son however, Malatesta da Verucchio (d. 1312), switched sides after the emperor's defeat near Parma in 1248, and became leader of the Guelphs while Guido I. of Montefeltro took the lead of the Ghibellines in the Marche and Romagna regions. Malatesta da Verucchio made himself sole master of the city ("signore") after the expulsion of the family's Ghibelline rivals, the Parcitadi, in 1295. His hunchback son Giovanni Malatesta is chiefly famous because he murdered his wife Francesca da Polenta and his younger brother Paolo in 1285, having discovered them in adultery, and the murder is recorded in Dante's Inferno as well as in a story by Giovanni Boccaccio. Malatestino I, Giovanni's brother, became capitano of the Guelphs of Bologna in 1296 and of Florence in 1303. In 1312 he destroyed his Ghibelline cousins' castle at Sogliano,
