In the 12th century, Emperor Frederick granted new arms to King Vladislaus II consisting of a silver lion on a red field, to symbolise his valor.

Later a second tail was added, for the help provided by the King Přemysl Otakar I fighting the Saxons (A legend from Dalimil's chronicle).

[3] During the first half of the 13th century the kings of Bohemia used a coat of arms bearing a black eagle in a silver shield.

[4][5][6][7][8] The oldest surviving full color depiction of the arms of Bohemia appears in the Passional of Abbes Cunegund from the 1310s.

The Silesian Eagle stems from the ruling dynasty of the Piasts and was first applied by Duke Henry II the Pious (1238–1241).
