Adeliza of Louvain (b. 1103)
Adeliza of Louvain, sometimes known in England as Adelicia of Louvain, also called Adela and Aleidis; (c. 1103 – March/April 1151) was Queen of England from 1121 to 1135, as the second wife of King Henry I. She was the daughter of Godfrey I, Count of Louvain.

Henry was some 35 years older than Adeliza, who was about 18 when they married. Having survived his legitimate son William Adelin, Henry hoped to have another with Adeliza and spent a lot of time with her. She seems to have been influential in the promotion of French poetry and other arts at court, but played little part in politics. Though otherwise successful, their marriage produced no children, and Henry decided to leave the throne to his daughter Empress Matilda. Adeliza was among those who swore to support her stepdaughter and did so during her struggle against Henry's nephew Stephen of Blois, who took the throne after Henry's death in 1135.

As queen dowager, Adeliza spent three years based in a convent, then married again and had seven children by William d'Aubigny, 1st Earl of Arundel. In 1150 she left her husband to move to the Affligem Abbey in Brabant, where she died the next year.
