Spyros posted site with naval maps from 14th till 15th century. i was always interested in serbian flag in medieval ages, so i searched if there is any flag except Dulcert's from which we know that it was red eagle on yellow. I found maps which date from 1439, 1440, 1456, 1466 in which we can also see the same flag. in 15th century serbian empire didn't exist anymore, it was the despotate. and in 1466 there was no serbia anymore. so what is that flag about? as we can see on those 4 maps, it points to durazzo (serbian drač), city in albania which was important trade colony of many kingdoms and republics. so i think that this flag is in fact durazzo flag, not the serbian. check it for your self
so i want to ask you, what should we do with serbia flag and coa? i posted poll
if you answer yes, then serbia will have nemanjic coa and oldest know red and blue flag
nemanjic coa
flag of serbia
if you answer no, than serbian coa and flag stays the same, red eagle on yellow background.
