Ermengarde or Erembourg of Maine, also known as Erembourg de la Flèche (died 1126), was the countess of Maine and lady of Château-du-Loir from 1110 to 1126..[1]
Erembourg was the daughter of Elias I, Count of Maine, and Mathilda of Château-du-Loire, daughter of Gervais II, Lord of Château-du-Loir. In 1109 she married the Angevin heir, Fulk V, called "Fulk the Younger". The marriage brought Maine under Angevin control, since she inherited the county from her father the following year and Fulk claimed it jure uxoris.[2] Their son inherited both Maine and Anjou, uniting the two counties.
She died in 1126, on either 15 January or 12 October. Shortly after her death, Fulk the Younger left his lands to their son Geoffrey. He set out for the Holy Land as a crusader, where he married Melisende, the heir of Baldwin II of Jerusalem, and became King of Jerusalem.[8]
