The origin of the Bindenschild has not been conclusively established, it possibly derived from the Styrian margraves of the Otakar noble family, who themselves may have adopted the colours from the descendants of the Carinthian duke Adalbero (ruled 1011–1035), a scion of the House of Eppenstein extinct in 1122.

According to the 18th century historian Chrysostomus Hanthaler, his grandson Duke Frederick II of Austria (1230–1246), nicknamed the "Quarrelsome" or the "Warlike", the last of the Babenberg dynasty, designed a new coat of arms in red-white-red after his accession—an attempt to prevail against reluctant local nobles and to stress his autonomy towards Emperor Frederick II.
