Sallustio Malatesta (c. 1450 - August 8, 1470[1]) was an Italian noble. 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.[3]
Isotta convinced Sigismondo to name him heir to Sigismondo's lordship, a choice also supported by Pope Paul II.
At Sigismondo's death in 1468, Isotta and Sallustio took control of his territory.[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] In 1470, he would have Sallustio assassinated.[5][6][1] Roberto would do the same to another of Sigismondo's sons, Valerio Galeotto Malatesta , in November of the same year.
