 After the Imperial Reform of 1495–1512, the Italian kingdom corresponded to the unencircled territories south of the Alps.Juridically the emperor maintained an interest in them as nominal king and overlord, but the "government" of the kingdom consisted of little more than the plenipotentiaries the emperor appointed to represent him and those governors he appointed to rule his own Italian states.The Habsburg rule in several parts of Italy continued in various forms but came to an end with the campaigns of the French Revolutionaries in 1792–1797, when a series of sister republics were set up with local support by Napoleon and then united into the Italian Republic under his Presidency.
