 Under the Constitution of the Italian Republic, the republican form of government cannot be changed by constitutional amendment, thus forbidding any attempt to restore the monarchy short of adoption of an entirely new constitution.The constitution also forbade male descendants of the House of Savoy from entering Italy.This provision was removed in 2002 but as part of the deal to be allowed back into Italy, Vittorio Emanuele, the last claimant to the House of Savoy, renounced all claims to the throne.
