 The analogous feminine title, "empress" (Latin "imperatrix"), was less frequently used for the consorts of the emperors.Only one reigning queen, Urraca, had occasion to use it, but did so sparingly.One of the earliest references to the Kingdom of Asturias, predecessor of the Kingdom of León, as an empire ("imperium") is in the "Chronicle of Alfonso III" (881), which says that King Silo (774–83) "subjugated the people of Galicia to his imperial rule" ("imperium").
