- Frederick of Bohemia
Frederick ( _cs. Bedřich) (died
25 March 1189 ) was the duke ofOlomouc from 1164 and thenduke of Bohemia from 1172 to 1173 and again from 1178 to his death. He was the son of King Ladislaus II, who abdicated in 1172 in his favour. However, he could not hold on to his principality, because he was approved of by neither the national diet nor the emperor, and was deposed in September the year following by the emperor at the Diet ofHermsdorf . TheEmperor Frederick I , godfather and namesake of Frederick, nominated Oldrich, son of Sobeslav I, but he renounced the throne in favour of Sobeslav II, friend of peasants, but enemy of both nobles and emperor.Frederick allied with the emperor and defeated Sobeslav at the battles of
Lodenice andPrague . The emperor recognised Frederick as an imperial prince, but he also raised the bishop of Prague, Henry Bretislaus, to princely status, making him a direct vassal of the emperor. He also appointed Conrad Ottomargrave overMoravia and thus divided the duchy into three parts dependent on him. When Frederick, who was practically a puppet of the emperor, died, he was succeeded by Conrad Otto.By his marriage to Elizabeth, daughter of
Geza II of Hungary , he had the following issue:
*Helena (b.1158), affianced to Peter, son ofManuel I Comnenus , in 1164
*Sophia (died25 May 1185 ), marriedAlbert, Margrave of Meissen
*Ludmilla (died14 August 1240 ), married Adalbert VI, count ofBogen , and thenLouis I, Duke of Bavaria
