County of Loon
In 1040, the Emperor Henry III recognized a county called Hasbania as being under the prince-bishop Nithard of Liège. This Hasbania may have been one of the smaller counties within the Hesbaye, but it seems that the important County of Loon, which had formed out of the Counties of Avernas and Hocht, was considered to be held under it. Much later, the County of Loon was integrated it with the Prince-Bishopric of Liège. Areas to the west of Loon came under the increasing power of the County of Leuven.
