frederick , duke of bohemia

frederick -lrb- -rrb- -lrb- died 25 march 1189 -rrb- was the duke of olomouc from 1164 and then duke of bohemia from 1172 to 1173 and again from 1178 to his death .
he was the son of king vladislaus 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 of hermsdorf .
the emperor frederick i , godfather and namesake of frederick , nominated oldřich , son of soběslav i , but he renounced the throne in favour of soběslav ii , sympathetic to the peasantry , but antagonistic to both nobles and emperor .
frederick allied with the emperor and defeated soběslav at the battles of lodenice and prague .
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 otto margrave over moravia 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 géza ii of hungary , he had the following issue : helena -lrb- b. 1158 -rrb- , affianced to peter , son of manuel i komnenos , in 1164 sophia -lrb- died 25 may 1185 -rrb- , married albert , margrave of meissen ludmilla -lrb- died 14 august 1240 -rrb- , married adalbert vi , count of bogen , and then louis i , duke of bavaria vratislaus -lrb- d. 1180 -rrb- olga -lrb- fl.c .1163 -rrb- margaret -lrb- died 28 august 1167 -rrb-
