On 7 March 1807, in the [[Cappella Palatina]] of the [[Palazzo dei Normanni]] in [[Palermo]], Charles Felix married by [[proxy marriage|proxy]]  [[Maria Cristina of Naples and Sicily]] (17 January 1779 - 11 March 1849), daughter of [[Ferdinand I of the Two Sicilies|Ferdinand IV]] King of Naples and Sicily and [[Maria Carolina of Austria]].

The marriage, which had originally been opposed by Charles Felix, had been arranged for dynastic reasons.  Neither Charles Emmanuel nor Victor Emmanuel had male children (the son of the latter had become sick and died in Sardinia), while the Duke of Montferrat and the Count of Morian were deceased, so Charles Felix had become the heir presumptive and therefore had to produce a male heir.

Although the marriage to Maria Cristina proved harmonious, she was unable to have children, forcing Victor Emmanuel to consider the succession of [[Charles Albert of Sardinia|Charles Albert]], [[House of Savoy-Carignano|Prince of Carignano]], from a collateral line of the House of Savoy.{{sfn|Montanelli|1971|p=309}}

After the fall of Napoleon and the return of Victor Emmanuel to Turin on 20 May 1814, Charles Felix joined him for a brief period before returning to Sardinia the following year with his wife.  He formally retained the role of Viceroy until 1821, although he returned to the court in Turin after a short period.
