Empress Matilda Empress Matilda (c. 7 February 110210 September 1167), also known as the Empress Maude, was the claimant to the English throne during the civil war known as the Anarchy. The daughter of King Henry I of England, she moved to Germany as a child when she married the future Holy Roman Emperor Henry V. She travelled with her husband into Italy in 1116, was controversially crowned in St. Peter's Basilica, and acted as the imperial regent in Italy. Matilda and Henry had no children, and when Henry died in 1125, the crown was claimed by Lothair II, one of his political enemies.
Judith of Bavaria (died 843) Queen Judith (797– 19 April 843), also known as Judith of Bavaria, was the daughter of Count Welf of Bavaria and Saxon noblewoman, Hedwig. She was the second wife of Louis the Pious, King of the Franks and Emperor of the Romans, which brought her the titles of queen and empress. Marriage to Louis marked the beginning of her rise as an influential figure in the Carolingian court. She had two children with Louis, a daughter Gisela and a son, Charles the Bald. The birth of her son led to a major dispute over the imperial succession, and tensions between her and Charles' half-brothers from Louis' first marriage. She would eventually fall from grace when Charles' wife, the new empress Ermentrude of Orléans, rose to power. She was buried in 846 in Tours.
