The Rosenberg family (Ro?mberkové in Czech, sg. z Ro?mberka) was a prominent Bohemian noble family that played an important role in Czech medieval history from the 13th century until 1611. Members of this family held posts at the Prague royal (and later imperial) court, and they were viewed as very powerful lords of the Kingdom of Bohemia. This branch of the Vítkovci clan was initially founded by Vítek III, the son of Vítek (German: Witiko) of Pr?ice.
Around 1250, the Vítkovci clan settled at the Ro?mberk Castle in the region of ?eský Krumlov, then about 1253 erected the ?eský Krumlov castle. The Krumlov castle thus became the residence of the Lords of Ro?mberk for the next three hundred years. It was the Ro?mberks who influenced the appearance of southern Bohemia to a great extent. The coat of arms and emblem of this family was represented by a red five-petalled rose on a silver field, which is still often seen in a considerable part of southern Bohemia.
Jind?ich's son, Oldrich II of Ro?mberk, was a member of the Bohemian nobility who defended the interests of Bohemian catholic nobility and of Sigismund, Holy Roman Emperor, during the times of the Hussite wars.
A daughter of Old?ich II was Perchta of Ro?mberk, who is identified with the Ro?mberks "White Lady" ghost tales, and current residents of the area still report seeing Perchta's spirit around the castle.
After Vilém's death in 1592, his younger brother, Petr Vok, assumed the position of reigning lord. In 1601, he was forced to sell the Krumlov castle to Rudolf II, Holy Roman Emperor. Petr Vok transferred his residence after the sale to T?ebo?, where he died in 1611. Petr Vok brought to a close the three-hundred-year-long reign of this illustrious dynasty.
