The Counts of Chiny were part of the nobility of Lotharingia that ruled from the 9th to the 14th century in what is now part of Belgium.
It has been proposed that the County of Chiny was created in the early 10th century out of the ancient county of Ivois. The county now forms part of the province of Luxembourg in present-day Belgium. The County of Chiny included the present-day towns of Chiny, Virton, Étalle, Florenville, Neufchâteau, Montmédy and Carignan, as well as the castles of Warcq on the Meuse, which was built in 971 by Otto, ancestor of the later Counts of Chiny.
It has also been proposed that there is a close relationship between the Counts of Chiny and the early counts of Looz, the counts of Verdun and the bishops of Verdun.[1][2][3]
The family of the counts of Chiny merged with the family of the counts of Looz. The final count of Chiny, Arnold IV de Rumingy, sold the county to the duke of Luxembourg, ending a dynasty of five hundred years.
