Empress Matilda / Empress Maud
Person Female Born 7/2/1102 Died 10/9/1167
Maud / Maude / Matilda was the daughter of King Henry I. On the death of her only sibling, William Adelin, her father named Matilda his successor but on his death Matilda's cousin, Stephen of Blois, claimed the throne. Battles ensued which Matilda won sufficiently to make arrangements for her coronation at Westminster, in 1141, but a mob of Londoners, who supported Stephen, ran her out of London. She eventually left for Normandy where she stayed and finally died but her son did achieve the crown in 1154 to become Henry II.
Had she been crowned she would have been England's first ruling queen. All English monarchs since 1154 have been descended from Matilda.
We don't understand the title 'Empress'; the title she used was 'Lady of the English'.
