 There also survive documents from Castile which make reference to the "imperator terrae" ("emperor of the land"), but the relevance of these was disputed by Mayer and Menéndez Pidal, who disagreed whether they referred to the Count of Castile or the King of León.The charters date from 968, when the count was Fernán González and the king was Ramiro III, and 1042, when the count, Ferdinand I, was also king.Another local count who with the help of Almanzor would briefly expel king Bermudo II and control the eastern part of the Kingdom of León as well as its capitol, would likewise express imperial pretensions.
