 Beginning in 1077 Alfonso instituted the use of the style "ego Adefonsus imperator totius Hispaniae" ("I, Alfonso, emperor of all Spain") and its use soon became regular.This title was used throughout the period 1079–81, which represents the peak of his imperial pretensions before his capture of the city of Toledo, ancient capital of the Visigoths.In 1080 he introduced the form "ego Adefonsus Hispaniarum imperator" ("I, Alfonso, emperor of the Spains"), which he used again in 1090.
