Louis II, Count of Loon

Louis II was count of Loon between the end of the 12th century to 1218.

He waged war against duke Henry I of Brabant for the inheritance of Albert III of Moha and the rights on Maastricht and Sint-Truiden. He had the rights of both cities, because he was regent of Duras.

Louis married Ada, Countess of Holland in 1203 after her father died and she inherited Holland. She waged war against her uncle William I of Holland, to defend her inheritance of Holland. Despite her marriage to Louis for extra protection, she was taken prisoner in Leiden and brought first to Texel and then to England.

Louis sought support from Hugo de Pierrepont, bishop of Liège, whom he helped to win at the battle of Steppes in 1213.

Louis was poisoned in 1218.
