Imiza of Luxembourg

Imiza of Luxembourg (also Irmentrude and Ermentrude) ( – after ), was a German noblewoman. She was the daughter of Frederick of Luxembourg, and the wife of Welf II of Swabia.

Life Imiza was the daughter of Frederick of Luxembourg and Ermentrude of Gleiberg. She was a direct descendant of Charlemagne, and her paternal aunt, Cunigunde was married to Emperor Henry II.

She was married to Welf II, Count of Swabia, probably in 1017. Imiza’s dowry included the estates of Mehring am Lech (near Augsburg) and Elisina (modern Solesino). Imiza probably received this property at the intervention of her aunt, Empress Cunigunde. Probably because of this connection Henry II also granted the Duchy of Carinthia to Imiza's son, Welf III (previously Carinthia had been ruled personally by the German emperors).

Imiza outlived her son, Welf III, who never married and had no children. Welf bequeathed his property to the monastery of Altdorf, where his mother had become abbess. She in turn gave the property to Welf IV, her grandson by her daughter Cunigunde.

Issue With Welf II, Imiza had two children: Cuniza (or Cunigunde) Welf III
