The coat of arms of Silesia and Lower Silesia displays a black eagle with silver crescent with a cross in the middle on its chest—the emblem of Silesian Duke Henry the Bearded (Zgorzelec)—on a golden background. It has been assumed in the tradition that the coat of arms and colors of Lower Silesia are simultaneously used as symbols of Silesia as a whole.
The coat of arms of Upper Silesia shows a golden eagle on a blue background.
In the Polish heraldry, the Silesian eagle is usually not crowned (with the exception of Cieszyn Silesia), in the Czech and German it is usually the opposite.
