Albert I of Habsburg () (July 12551 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. 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. Biography From 1273 Albert ruled as a landgrave over his father's Swabian (Further Austrian) possessions in Alsace. In 1282 his father, the first German monarch from the House of Habsburg, invested him and his younger brother Rudolf II with the duchies of Austria and Styria, which he had seized from late King Ottokar II of Bohemia and defended in the 1278 Battle on the Marchfeld. By the 1283 Treaty of Rheinfelden his father entrusted Albert with their sole government, while Rudolf II ought to be compensated by the Further Austrian Habsburg home territories – which, however, never happened until his death in 1290. Albert and his Swabian ministeriales appear to have ruled the Austrian and Styrian duchies with conspicuous success, overcoming the resistance by local nobles. King Rudolf I was unable to secure the succession to the German throne for his son, especially due to the objections raised by Ottokar's son King Wenceslaus II of Bohemia, and the plans to install Albert as successor of the assassinated King Ladislaus IV of Hungary in 1290 also failed. Upon Rudolf's death in 1291, the Prince-electors, fearing Albert's power and the implementation of a hereditary monarchy, chose Count Adolf of Nassau-Weilburg as King of the Romans. An uprising among his Styrian dependents compelled Albert to recognize the sovereignty of his rival and to confine himself for a time to the government of the Habsburg lands at Vienna. He did not abandon his hopes of the throne, however, which were eventually realised: In 1298, he was chosen German king by some of the princes, who were bothered about Adolf's attempts to gain his own power bases in the lands of Thuringia and Meissen, again led by the Bohemian king Wenceslaus II. The armies of the rival kings met at the Battle of Göllheim near Worms, where Adolf was defeated and slain. Submitting to a new election but securing the support of several influential princes by making extensive promises, he was chosen at the Imperial City
