Sallustio Malatesta

He was the son of Sigismondo Pandolfo Malatesta, lord of Rimini, and Isotta degli Atti.

[2] At first, Isotta was Sigismondo's mistress, but after the death of his wife Polissena Sforza, they would marry.

[4] Roberto Malatesta, an illegitimate son of Sigismondo, opposed his father's decisions.

He would take control of Rimini with assistance from Milan, Florence, and Naples.

[5][6][1] Roberto would do the same to another of Sigismondo's sons, Valerio Galeotto Malatesta [it], in November of the same year.
