By the middle of the 13th century, the counts of Luxembourg had managed to considerably gain in wealth and power, and had expanded their territory from the river Meuse to the Moselle. By the time of the reign of Henry V the Blonde, Bitburg, La Roche-en-Ardenne, Durbuy, Arlon, Thionville, Marville, Longwy, and in 1264 the competing County of Vianden (and with it St. Vith) had either been incorporated directly or become vassal states to the County of Luxembourg. The only major setback during their rise in power came in 1288, when Henry VI and his three brothers died at the Battle of Worringen, while trying unsuccessfully to also add the Duchy of Limburg into their realm. But despite the defeat, the Battle of Worringen helped the Counts of Luxembourg to achieve military glory, which they had previously lacked, as they had mostly enlarged their territory by means of inheritances, marriages and fiefdoms.
