Count Balderic of Upladium (died 5 June 1021) was a Rhineland count in the Holy Roman Empire, who held various estates stretching from the forest region of Drenthe in the north, to the area near Cologne, on both sides of the river Rhine.
Balderic and his wife Adela of Hamaland were heavily involved in feuds among the nobility in the region where the rivers Rhine and Maas converge, near the present day border of the Netherlands and Germany. At first he fought against Adela in the feud between her and her sister, Liutgard of Elten, perhaps as Luitgard's vassal. Together with Godizo son of Richizo, a relative of the sisters, he successfully destroyed Adela's fort. By 996, Liutgard was dead, and he had become the second husband of Countess Adela.[1]
In the context of the bigger feuds which affected much of the Holy Roman Empire during the reign of Henry II, Balderic was a political ally of Gerhard of the Moselle, Count of Metz, and Count Reginar III, who was fighting to establish himself as a count near the region of Pagus of Brabant. This group were allies of the rebellious Luxembourg branch of the House of Ardenne, and also supported by Heribert the Bishop of Cologne.[2]
