Pagus of Liugas

Liugas, Leuwa-gau, or Luihgau, was a small pagus or gau from the late 8th to mid-11th centuries, east of the Meuse (or Maas) river roughly between Liège, Maastricht, and Aachen, an area where Germany, Belgium and the Netherlands meet today. There were only a small number of mentions made of this territory, all between 779 and 1059.

Much of Liugas was located in the modern Belgian province of Liège in Belgium and South Limburg in the Netherlands. Based on some of the many spelling variants, it was traditionally believed to have been named after the nearby city of Liège. This is now seen as incorrect by modern scholars.

It was administered by one or more counts. There are two counts associated with the area in the 10th century, Sigehard and Richar. After 1000 there are also some records which indicate that a Count Theobald or Thibaut held a county there. After him, the area was divided into new jurisdictions such as those based in Valkenburg, Limbourg-sur-Vesdre, Voeren and Dalhem.
