Cruz de Borgoña
When the House of Habsburg took the Spanish throne by mid-16th century each military company had its own flag in which appeared usually the arms of its commander over the Cross of Burgundy. In order to represent the King, they used to have another one, the "Coronela", during the reign of Charles I (Charles V as Holy Roman Emperor) that was made of yellow silk (the imperial color) with the embroidered imperial shield.
