When did Otto V, Duke of Bavaria's father become the King of the Romans?
Otto V, Duke of Bavaria Otto V the Bavarian, Duke of Bavaria (1340/42 – 15 November 1379), was a Duke of Bavaria and Elector of Brandenburg as Otto VII. Otto was the fourth son of Holy Roman Emperor Louis IV by his second wife Margaret II of Avesnes, Countess of Hainaut and Holland.
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.
