The Magic Sword (1962)
Also, between 800 A.D. and 1806, there was an entity called the "Kingdom of Italy" which consisted of mostly of Northern and Central Italy except for Venice. It was one of the three constituent kingdoms of the so called Holly Roman Empire along with Germany and Burgundy. They were nominally ruled by the German Holy Roman Emperor, but in reality, central government was usually non-existent so the "Kingdom of Italy" only existed on paper.
Still, "Sir Anthony of Italy" would not have been an incorrect title.
