Elections took place in 1919, 1921 and 1924: in this last occasion, Mussolini abolished the proportional representation replacing it with a block voting system on national bases, which gave to the Fascist Party the absolute majority of the Chamber seats.
Valimised toimusid aastatel 1919, 1921 ja 1924: viimasel korral tühistas Mussolini võrdelise valimissüsteemi ja asendas selle Acerbo seadusega, mis andis fašistlikule parteile absoluutse enamuse parlamendis.
