Leopold I of Austria (Habsburg)

Leopold I (4 August 1290 – 28 February 1326) from the House of Habsburg was Duke of Austria and Styria – as co-ruler with his elder brother Frederick the Fair – from 1308 until his death. Born at Vienna, he was the third son of King Albert I of Germany and Elisabeth of Gorizia-Tyrol, a scion of the Meinhardiner dynasty.

After the death of his eldest brother Duke Rudolph III in 1307 and the assassination of King Albert in 1308, Leopold became head of the Habsburg dynasty and administrator of the Swabian home territories, where he started a retaliation campaign against his father's murderers. The energetic man converged with the royal House of Luxembourg and accompanied King Henry VII on his Italian campaign. In 1311 he helped to suppress a Guelph revolt at Milan under Guido della Torre and to lay siege to the city of Brescia.

Upon Emperor Henry's death, he strongly supported his brother Frederick in the 1314 election as King of the Romans. Despite all efforts (and bribes), the Habsburgs only gained the votes of four Prince-electors, while Louis IV of Wittelsbach, with support of the Luxembourgs, was elected by five. In the following armed conflict between the rivals, the forces of Leopold were supportive of his brother's claims. In his ancestral homeland however, he incurred a decisive defeat by the Swiss Confederacy at the 1315 Battle of Morgarten.
