Arnold II, Count of Loon

Arnold II (or Arnulf, Arnoul) (died 1146), Count of Looz, son of Arnold I, Count of Looz, and Agnes von Mainz, daughter of Gerhard I, Count of Rieneck, and Helwig von Bliescastel. He is distinguished from his father of the same name by historians who note records for counts named Arnold or Arnulf between 1179 and 1141. The first Arnold must have died between 1125 when Count Arnold appears in a record with his son also named Arnold, and 1135, when a new Count Arnold appears with his own son and successor Louis.

Between these two dates, in 1129, Gislebert, Count of Duras, sought to seize the property of the Abbey of Sint-Truiden. (Giselbert was a cousin, the grandson of his namesake Giselbert, Count of Looz.) A war developed between Giselbert and the supporters of the abbot Radulphe, whose allies included Arnold (possibly Arnold I was still alive), Théoger, Bishop of Metz, Alexander I of Jülich, Bishop of Liege, and Waleran II, Duke of Lower Lorraine.Gislebert's supporters included his brother-in-law Godfrey the Bearded, Count of Louvain, and Thierry of Alsace, Count of Flanders. The decisive battle took place on 7 August 1129 at Wilderen where Gislebert and his allies were defeated, but peace did not return in 1131.

He founded the Abbey of Averbode, giving home to the Order of Canons Regular of Prémontré that St. Norbert had created.

Arnold had an outstanding reputation among his contemporaries, frequently being the arbiter in disputes between neighbors. In particular, he succeeded in bringing about a reconciliation between Dirk VI, Count of Holland, and Giselbert's son Otto II, to get Herman van Horne, grandson of Emmo, Count of Looz, recognized as Bishop of Utrecht. He was welcomed with great distinction at the court of the emperors of Germany, and his name frequently appears among the witnesses mentioned in the charters granted by Emperors Henry IV, Henry V and Lothair II, and King of Germany Conrad III.

According to a document which is possibly spurious, Arnold married Aleide. Arnold is proposed to have had five children:

• Louis I, Count of Looz
• Gerard (d. after 1138), Count of Rieneck
• Gottschalk (d. after 1138)
• Imagine, Abbess of Susteren in 1174
• Jean de Looz, Seigneur de Ghoer, married to Sophie.

Arnold was succeeded as Count of Looz by his son Louis.
