 After Mussolini's March on Rome, King Victor Emmanuel III refused to sign a decree to declare a state of siege and instead asked Mussolini to form a new government.The King's decision was within his powers under the Italian constitution, but contrary to the parliamentary practices of the Italian liberal state, as the Fascist Party had only a small minority of the parliamentary deputies.After the invasion of Italy by Allied forces in 1943, Mussolini's Grand Fascist Council, with the co-operation of the King, overthrew Mussolini and established a new government headed by Marshal Pietro Badoglio.
