John I of Isenburg-Limburg

John I of Isenburg-Limburg, "The blind Lord" (died September 29, 1312) was from 1289 Count of (Isenburg-) Limburg and the head of the House of Limburg. The core territory of the Lordship of Limburg consisted of the city of Limburg an der Lahn and several surrounding villages. In the City Chronicle of Limburg by Tilemann Elhen von Wolfhagen, written before 1402, John was referred to as the "Blind Lord." What is this name means, however, is unclear, because no sources refer to John being physically blind. Probably John had an eye disease in his old age and was thereby visually impaired. Life John’s father, Gerlach I of Limburg, had founded the House of Limburg and sought to secure dynastic connections with neighboring noble families. John’s sister Imagina was married with the Count, later King of Germany, Adolf of Nassau. His second sister Agnes was married to Henry of Westerburg, the brother of the Siegfried II of Westerburg, the Archbishop of Cologne. In 1288 John participated in the Battle of Worringen on the side of Siegfried of Westerburg. After the death of his father in the Black Forest on a military campaign of King Rudolph I of Habsburg, John inherited Lordship of Limburg.
