According to Baumgarten, the wife of Duke Boleslav III was Predslava of Kiev, daughter of Vladimir I "Velikiy/the Great" Grand Prince of Kiev.There is no indication about the date of such a marriage if it ever took place.[Duke Boleslav has been suggested as the possible husband of lfgifu of Wessex, daughter of Edward "the Elder" King of Wessex & his second wife lfleda ---.Hroswitha of Gandersheim describes her as "Adiva younger in years and likewise inferior in merit" to her older sister Eadgyth, whom she accompanied to Germany to provide an alternative choice of bride for Otto of Germany, who has not been identified.After King Heinrichs succession as duke of Carinthia in 1310, the Bohemian crown passed to Jean Comte de Luxembourg, elected as Jan King of Bohemia, who at the same time married the older sister of King Wenzel III (see Chapter 4).The Luxembourg dynasty retained the Bohemian throne until the death in 1437 of King Zikmund.The Luxembourg kings of Bohemia leveraged their territorial strength along the western and eastern borders of the Holy Roman Empire to acquire a position of considerable power in Germany.King Jan imposed Bohemian suzerainty on Silesia in 1327 and in 1334 installed his son Karl as Markgraf of Moravia.
However, three pieces of information apparently relating to Predslava show that she was still living at the court of Kiev during the period [1015/18] and that she was probably unmarried at the time.
After King Wenzel III was murdered in 1306, Albrecht I King of Germany engineered the succession as king of Bohemia of his son Rudolf III Duke of Austria, who had married King Wenzels stepmother.
King Rudolf died later in 1307, at which time Heinrich von Grz, son of Meinhard II Duke of Carinthia, was appointed to succeed (see Chapter 3).
His descendants continued to rule Bohemia until the death in 1306 of the last descendant in the male line.
emysl Otakar I was crowned king in 1198, and his descendants continued to rule as kings.He succeeded in 935, after murdering his brother, as BOLESLAV I "der Grausame" Duke of the Bohemians.
