Albert I of Germany

Albert I of Habsburg (German: Albrecht I.) (July 1255 – 1 May 1308) was a Duke of Austria and Styria from 1282 and King of Germany from 1298 until his assassination. He was the eldest son of King Rudolf I of Germany and his first wife Gertrude of Hohenberg. He is sometimes referred to as 'Albert the One-eyed' because of a battle injury that left him with a hollow eye socket and a permanent snarl.
