The July Revolution of 1830 in France also affected the Italian politics.
The Papal States were very badly affected. From the Papal States, the movement spread to Piedmont, Parma and Modena. However, the rising were everywhere successful.
Pope Gregory XVI asked for the help of Austria. Metternich sent the Austrian armies into Italy and the Papal States were occupied by the White coats.
Order was restored and the authority of the Pope was re-established.
Francis IV was restored to his throne in Modena and Marie Lousie in Parma.
However, as soon as the Austrian troops left Italy, fresh revolts broke out and they had to return once again. At this time, France also sent an army to occupy Ancona (1832) and for 6 years Austrian and French troops continued to confront each other in the Papal States.
The insurrections failed because the democratic efforts were disunited and not systematic.
The people were not ripe for revolution. Unity was the cry of only a few leaders and not the creed of the masses.
However, one thing was clear and that was the weakness of the reactionary States in Italy. They were saved only by the intervention of Austria.
