After Rudolf's death in 1291, Adolf and Albert were two further weak kings who were never crowned emperor. Adolf of Germany (c. 1255 – 2 July 1298) was Count of Nassau from about 1276 and elected King of Germany (King of the Romans) from 1292 until his deposition by the prince-electors in 1298. He was never crowned by the Pope, which would have secured him the title of Holy Roman Emperor. He was the first physically and mentally healthy ruler of the Holy Roman Empire ever to be deposed without a papal excommunication. Adolf died shortly afterwards in the Battle of Göllheim fighting against his successor Albert of Habsburg. Albert I of Germany (July 1255 – 1 May 1308), the eldest son of King Rudolf I of Germany and his first wife Gertrude of Hohenberg, was a Duke of Austria and Styria from 1282 and King of Germany from 1298 until his assassination.
