Conan III, also known as Conan of Cornouaille and Conan the Fat (Breton: Konan III a Vreizh, and Konan Kerne; c. 1093–1096 – September 17, 1148) was duke of Brittany, from 1112 to his death. He was the son of Duke Alan IV and Ermengarde of Anjou.

Conan III allied himself with Stephen of England in Stephen's war against the dispossessed Empress Matilda.[a][b]

Family[edit]

He married Maud, an illegitimate daughter of King Henry I of England before 1113. Conan and Maude had three children:

  • Hoel – disinherited from the Ducal crown; Count of Nantes;
  • Bertha (b.c. 1114) – married Alan of Penthièvre;[c] upon Alan's death in 1146, she returned to Brittany; and
  • Constance

Succession[edit]

On his death-bed in 1148, Conan III disinherited Hoel from succession to the Duchy, stating that he was illegitimate and no son of his. By this surprise move Bertha became his heiress and successor. However, Hoel was to retain the county of Nantes.

Notes[edit]

  1. ^ Stephen created Conan's son-in-law Alan 1st Earl of Richmond. Alan rode by the side of Stephen in the Battle of Lincoln.
  2. ^ The Earldom of Richmond was inherited by Alan's son, and Conan III's grandson Conan IV. It would remain in the Ducal house of Brittany for some time.
  3. ^ King Stephen of England created Alan 1st Earl of Richmond and 1st Earl of Cornwall
