Engelbert III of Istria

From Wikipedia, the free encyclopedia

Engelbert III (died 6 October 1173) was the Margrave of Istria[1] and Carniola[2] from 1124 until his death. He was a Sponheimer, the eldest son of Engelbert II and Uta of Passau. He succeeded his father in Istria and Carniola when his father was raised to the Duchy of Carinthia. He is sometimes numbered Engelbert II of Istria.

From 1135 to 1137 Engelbert was Margrave of Tuscany. In 1156, he witnessed the granting of the Privilegium Minus creating the Duchy of Austria.

Engelbert married Matilda, youngest daughter of Berengar I of Sulzbach. He was thus a brother-in-law of Gertrude, wife of Conrad III of Germany, and Irene, wife of Manuel I Comnenus. Matilda died late in 1165. They had four children:

  • Henry, who inherited Carinthia from his grandfather in 1144
  • Urlic, Count of Laibach
  • Godfrey, a pries
  • Herman II, succeeded his brother in Carinthia
