Design
The coat of arms of the Silesian Voivodeship consists of a blue Old French style escutcheon (shield) with square top and pointed base. It features a yellow (golden) eagle with raised wings and head turned left. It wears a yellow (golden) crown on its head. It was based on the historical coat of arms used by Jan II the Good, duke of Silesia.

Silesian duchies
The first coat of arms recorded to be used by a ruler in the area of Upper Silesia, that featured an eagle, belonged to duke Casimir I of Opole, member of the Silesian Piast dynasty, who ruled the Duchy of Opole and Racibórz, from 1211 to 1230. Such design was recorded in a document from 1222, marked with Casimir's seal, that featured him holding a shield with an eagle on it. It remains unknown what colours the coat of arms had. The first known usage of a yellow (golden) eagle in the coat of arms had been recorded in the 1257 and 1260 seals of duke Vladislaus I of Opole, ruler of the Duchy of Opole and Racibórz. Since then, the coat of arms had been used by his descendants.

Over time, the coat of arms had been modified, with major change being appearance of the crown on eagle's head. It appeared for the first time in the coat of arms of duke Casimir of Bytom in 13th century, and became the permanent feature of the design in late 14th century, beginning with duke Bolko IV of Opole, and being used until the end of the Opole and Racibórz line of the dynasty, in 1532, with the death of duke Jan II the Good. In his will, he had written to give his coat of arms to the society of the Duchy of Opole and Racibórz, making it a symbol of the whole area and its population, rather than a symbol of royal family.

In the bottom portion of the escutcheon was placed crossed yellow (golden) hammer and pick. In the middle of the escutcheon was placed a yellow (golden) scythe blade. The coat of arms was depict motives characteristic to Upper Silesia, including the golden eagle on a blue background, a scythe symbolizing agriculture, and crossed hammer and pick symbolizing the mining industry.
