County of Loon
For much of its recorded history, most of what is now called Belgian Limburg was the County of Loon (). Loon was a medieval county, and when the line of the Counts died the county became a lordship held by the Prince-bishop of Liège. It was still often referred to as the "land of Loon" (). The original capital of medieval Loon is today officially called Borgloon, but the capital of the modern province is now Hasselt.
