Sicily was a democratic nation between 1983 up until 2002 (In reality an illiberal one), in 2002 a expansionistic and militaristic faction would emerge among some far right politicians and the most extremist members of the armed forces, claiming that the political class has become soft and weak. In 2002 the Two Sicilies would become a dictatorship with a military junta or a civilian dictator. I'm thinking that after the 2nd Sicilian War the population of the republic, alongside moderate and liberal members of the Armed Forces would stage a revolution and a coup d'etat for ousting the dictatorship and replacing it with a full democracy. Ending his militaristic goals and starting to open relationships with northern Italy.
