How accurate and comprehensive is this Quaternion Eagle standart from 16th century? Is it representing whole fiefdoms of HRE or just major ones listed?
Ive been seeing this online for a long time, especially on Wikipedia and we know how fragmanted HRE were especially in high Medieval ages. So how Quaternion Eagle is comprehensive at all? Or is it just representing some major fiefs on the heart of HRE? What do you think?
