Empress Matilda
Empress Matilda (c. 7 February 1102–10 September 1167), sometimes called Empress Maud, was the second child of Henry I of England and Matilda of Scotland. Her brother, William Adelin, died in the wreck of the White Ship in 1120. This made Matilda the hereditary heir to the English throne. At her father's death in 1135, her cousin King Stephen rushed to take the throne. This led to a civil war between Stephen and Matilda, known as the Anarchy.
