Born in Carrarc, Italy in 1787, he became a supporter of liberal ideas in Italy until he fled the Austrian control in 1805.
In Geneva he became professor of criminal law and Roman law.
He was elected to the Representative Council, and later to the Federal
Government, where he proposed, unsuccessfully, a constitutional bill called the
“Rossi Pact”, which is the origin of the Federal State of 1848.
Disappointed, he went to live in France where he became professor at the “Collège de
France” before being sent to Rome as Ambassador. In 1848 the new Pope Pious IX named him Prime Minister of the Papal
States. He was assassinated two
months later by Italian revolutionaries.
