To depose the weak parliamentary democracy, Deputy Mussolini (with military, business and liberal right-wing support) launched the PNF March on Rome (27–29 October 1922) coup d'état to oust Prime Minister Luigi Facta and assume the government of Italy to restore nationalist pride, restart the economy, increase productivity with labor controls, remove economic business controls and impose law and order. On 28 October, whilst the "March" occurred, King Victor Emmanuel III withdrew his support of Prime Minister Facta and appointed PNF Leader Benito Mussolini as the sixth Prime Minister of Italy.
