Queen of Italy (regina Italiae in Latin and regina d'Italia in Italian) is a title adopted by many spouses of the rulers of the Italian peninsula after the fall of the Roman Empire. The details of where and how the ruling kings ruled are in the article about them. The elective dignity of Roman Emperor was restricted to males only; therefore, there was never an Italian Queen regnant, though women such as Adelaide of Italy and Theophanu and Maria Theresa of Austria, who controlled the power of ruling, ruled as de facto Queens Regnant.
