Conrad I, Count of Luxembourg

Seal of Conrad I of Luxembourg. The Latin inscription on the border of the seal reads: CONRARDVS COMES DE LVCELEMBVRCH

Conrad I (c. 1040 – 8 August 1086), Count of Luxembourg, was the first count of Luxembourg (1059–1086), succeeding his father Giselbert of Luxembourg.

He was embroiled in an argument with the archbishop of Trier as to the abbaye Saint-Maximin in Trier which he had avowed. The archbishop excommunicated him and Conrad had to make honourable amends and set out on pilgrimage for Jerusalem. He died in Italy on the return journey.

He founded many abbeys:

• the abbaye d'Orval in 1070, with Arnoul I, count of Chiny.
• the abbaye d'Altmünster in 1083
