The Young Italy was only a minority movement and he was the die-hard enemy of monarchism.
Federation was another line when unification was to be under the Pope as advocated by Goberti. However, the Papal States as marked by religious conservatism was greatly doubted for her sincerity. And finally it proved useless when the movement was betrayed by the Pope.
Moreover, the Piedmontese army was also one of the potential source of unification, but its reluctance to first social concession and political liberty weakened her cause when the Emperor feared and hated the massed more than he feared Austrian power. When liberty and unity were to be achieved at the same time, the emperor feared the former and finally abandoned both came to conservatism prevented a common union between the throne and the people to achieve any effective movement against Austrian rule in Italy.
Moreover, the uncoordinated and ineffective effort of the secret societies, for Carbonari did not achieve. Gicat's success when Austrian power was strong but the sects unity and forced was weak. As Metternich said "the seats are not nearly so dangerous as we may fear." These uncoordinated and piece-meal effort was doomed to failure.
In conclusion the question before Italy was foreign rule on independence, unity in federation, political change from above or social and economic revolution from below. All these were undecided and even the road was unclear. It was doubtful whether they could succeed with no foreign aid but only an ant-revolutionary Holy Alliance. The main forces of Risorgimento, that is, Romanticism with the intellectual work of Lesparda and Mazzini and industrialism with little economic basis and an awakened education were still weak, uncoordinated, vague in goal and divided in leadership and this was no clear effort to know which method was to the employed.
In revolution of 1848 frustrated these uncoordinated and contradicted effort, but the movement had not gone to far to be stopped.
