State country (German: Freie Standesherrschaft; Czech: stavovské panství; Polish: państwo stanowe) was a unit of administrative and territorial division in the Bohemian crown lands of Silesia and Upper Lusatia, existing from 15th to 18th centuries.
Some of the state countries were highly autonomous, they had their own legal code and their lords were vassals of the king himself, not of the local dukes or princes.
As a ceased fief their possessions would fall to the Bohemian crown and sometimes were granted to lords of lesser nobility not affiliated with the ducal Piast family.
In years 1571-1573 Wenceslaus III Adam, Duke of Cieszyn sold several parts of the Duchy of Cieszyn forming state countries: The estates of Upper Lusatia: held the status of a state country under the Bohemian crown, represented in the Landtag diet, where they met the strong opposition of the Lusatian League.
Together with whole Lusatia they came under the overlordship of the Saxon Electorate by the 1635 Peace of Prague: Muskau and Hoyerswerda were incorporated into the Prussian Province of Silesia according to the Final Act of the Vienna Congress in 1815.
