So, between 1821 and 1822 the newly independent Mexico was searching for a European prince to crown Emperor, after the refusal of Ferdinand VII, preferably a Bourbon. During the same period, Charles Albert of Savoy-Carignano had been exiled to Florence after his involvement in an attempt to to force the King of Sardinia to accept a constitution.
So let's say that, after not being able to recruit Bourbon prince, and hearing of the above, decide to offer the throne to Charles Albert, who, maybe excluded from the line of succession, as the then king, Charles Felix, wanted, accepts it.
