Cesare wished to marry Carlotta, the daughter of the king of Naples, but both she and her father resolutely refused an alliance with "a priest, the bastard of a priest."
In May 1867 he married the princess Maria Carlotta del Pozzo della Cisterna.
His tragedy Francesca da Rimini, was brought out with success by Carlotta Marchionni at Milan in 1818.
Afterwards he became imperial commissioner of emigration to the emperor Maximilian of Mexico, and started building "New Virginia" and a "Carlotta" colony in Mexico.
Maximilian and Carlotta had been forwarned.
