Giannone, Pietro (1676–1748)

Italian historian whose attack on the Roman Catholic Church, Storia civile del regno di Napoli1723, led to his banishment.

Giannone studied law and practised as a barrister at Naples. He retired to Vienna, Venice, and finally Geneva, where he wrote his diatribe, Il Triregno, against papal authority. He was enticed into Savoy, arrested by order of the king of Sardinia, and confined at Turin till his death.
