Hroznata of Úžice was a Moravian nobleman, Highest Burgrave of the Kingdom of Bohemia between 1284 and 1286, and the founder of the Talmberk family.

[1] Hroznata was in the service of King Wenceslas II, for which he was granted land north of the Sázava River around Úžice.

The castle was first indirectly documented in 1297 through the name of Vilém of Talmberk, a son or nephew of Hroznata.

[3] After a dispute with Bishop Tobiáš of Bechyně [cs] in support of Záviš, Hroznata and his sons were declared outlaws and much of their property was confiscated.

[4] The wax seal of Hroznata of Úžice, attached to a deed dated 24 May 1284, contains the two water lilies of the Kounice family.
