One of the followers of the Holy Roman Emperor Frederick II was Margrave Henry III. of Meissen (1218-1288). He held court with splendid tournaments, composed sacred music and was renowned for his lavish court. So he got the nickname "illustris" the Illustrious.
Margrave Otto IV of Brandenburg (1266-1309) is known as "the pfile". He was met at the siege of the Stass Bode at the head of an arrow and let the arrow head - from mistrust of the doctors - a year in the wound.
