The County of Savoy and its possessions ( red) within the Holy Roman Empire around the middle of the 13th century. The cream area highlights the rest of the Kingdom of Burgundy. Note that some of Savoy's possessions lie outside of that kingdom (instead being part of the Kingdom of Italy). Savoy proper is the westernmost of the territories. The unmarked territory directly to the northwest of Savoy proper, Bresse, was acquired in 1272.
While the Arelat remained a titular kingdom of the Holy Roman Empire, Humbert's descendants—later known as the House of Savoy—maintained their independence as counts. In 1046, his younger son Otto married Adelaide, daughter of Ulric Manfred II, marquis of Susa. When she inherited her father's lands in preference to other, male, relatives,[note 1] he thereby acquired control of the extensive March of Turin. This was then united with Savoy upon his inheritance from his elder brother.[3]
