Life
Adelaide was a daughter of the Duchy of Bavaria, Bavarian margrave Diepold III, Margrave of Vohburg, Diepold III of Vohburg (c. 1079 – 1146), probably from his first marriage with Adelaide (''Adelajda''; c. 1091 – 1127), a daughter of the History of Poland during the Piast dynasty, Polish duke Władysław I Herman and Judith of Swabia. Since the days of Emperor Henry IV, Holy Roman Emperor, Henry IV, her father's ancestors ruled over the Egerland territory in the Bavarian March of the Nordgau, which, however, was seized by King Conrad III of Germany upon the margrave's death in 1146. To secure his hold on the Egerland, Conrad III married his nephew Frederick I, Holy Roman Emperor, Frederick of Hohenstaufen to Diepold's daughter, Adelaide, before 2 March 1147 in the city of Cheb, Eger. Frederick had just returned from the Second Crusade; he succeeded his father Frederick II, Duke of Swabia, Frederick the One-Eyed as Duke of Swabia one month later and added his wife's extended dowry to his estates. Adelaide and Frederick's marriage was not successful, however. According to some later sources, this was because Adelaide committed adultery. Adelaide rarely made public appearances and was not present for Frederick's Imperial election, election as the successor of his paternal uncle, Conrad III, on 4 March 1152, nor for his coronation as List of German monarchs, King of Germany at Aachen Cathedral five days later. Adelaide was Frederick's queen consort, but the couple remained childless. In 1153 Frederick petitioned Pope Eugene III for an annulment. The separation was granted and confirmed by the Bishopric of Constance, Bishop of Constance in March 1153; the justification given on grounds of consanguinity. Frederick immediately began to court the Byzantine Empire, Byzantine princess Maria Komnene, Queen of Hungary, Maria Komnena, though to no avail. No longer a queen, Adelaide, apparently unhampered by her former husband, soon after entered into a morganatic marriage with Dietho of Ravensburg, a ''ministerialis'' in the service of Duke Welf VI. The marriage produced several children. Dietho died about 1187; Adelaide died shortly afterwards at the Premonstratensians, Premonstratensian abbey of Weissenau Abbey, Weissenau near Ravensburg.References
