 The Leopoldian line received the Duchy of Styria, ruled by Austria according to the 1186 Georgenberg Pact, as well as the duchies of Carinthia and Duchy of Carniola, the County of Tyrol, and the original Habsburg estates in the former Duchy of Swabia.Duke Leopold had four sons; upon his death in 1386 he was initially succeeded by the eldest, William the Courteous, who ten years later had to cede Tyrol and the Swabian estates to the second-born son Leopold IV.Upon William's death in 1406, the remaining territories of Styria, Carinthia and Carniola were inherited by the third-born Ernest the Iron and became known as Inner Austria.
