So I was looking for a good Spanish Character to play on CKII and ended up stumbling onto the title Imperator totius Hispaniae or Emperor of all Spain and was surprised. I had no idea that any Spanish ruler, besides Charles V, used the title of Emperor or Empress. So if the title existed why did none of the rulers of Unified Spain use the title? I mean was there a particular reason or was the title forgotten? I could see Charles V revived the title for his son Philip, after he failed to get Philip elected Holy Roman Emperor. Or perhaps Philip after he became King of Portugal. Or even Isabella and Ferdinand could revive the title after the conquest of Granada.
