The new king was affected by the [[July Revolution]], which had deposed Charles X of France and led to the accession of [[Louis Philippe]], an ex-revolutionary, and as a result, he decided to make an alliance with the [[Austrian Empire]]. The treaty, signed on 23 July 1831 and ratified in 1836, entrusted the defence of the Kingdom of Sardinia to Austria. However, in the event of war, the commander of the joint forces was to be Charles Albert. He wrote to the Austrian ambassador, Ludwig Senfft von Pilsach (1774–1853), "... the most beautiful day of my life will be the day on which there is war with France and I have the good fortune to serve in the Austrian army."<ref>{{harvnb|Bertoldi|pp=173–174}}</ref>

In accordance with this [[legitimist]] position, Charles Albert lent support to his close friend [[Marie-Caroline de Bourbon-Sicile, duchesse de Berry]] in December 1823 when she sought to place her son, [[Henri, Count of Chambord|Henri]], on the French throne. She was the widow of the [[Duc de Berry]], second son of Charles X, whose eldest son, [[Louis Antoine, Duke of Angoulême|Louis Antoine]] had renounced the throne. Henri's claim to the throne had been denied by the king.<ref>{{harvnb|Bertoldi|pp=174–175}}</ref>

Despite the advice of the French ambassador to exercise prudence, in 1832, Charles Albert loaned Marie-Caroline a million francs and placed a steamer at her disposal for transporting legitimist volunteers to France. The plot was discovered and failed; the steamer was stopped at Marseille and the volunteers were defeated at [[Vendée]] in a few hours. Marie-Caroline fled, but was soon arrested in Nantes and imprisoned in the Citadel of [[Blaye]], near [[Bordeaux]].<ref>{{harvnb|Bertoldi|pp=175–176}}</ref>
