The House of Rosenberg 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 court, and 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 Witiko of Prčice.
