Facts and Events
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.
