900’s-1204 Roman Empire Cross Flag
For historicity, use this flag during the given time period stated in the title.
The flag here consists of the Roman flag that had been used since the abandonment of the Khi-Rho standard started by Constantine I, a red banner and a golden cross, which later had four golden X’s added to it (these being the Greek K’s, they relating the Khristos, or Christ), then the X’s were replaced by four golden circles (the edition used in the mod). If anyone knows what these circles may have symbolized, please let me know. Other flags in the picture above are military flags, save the one with the golden cross.
Upon the recapture of Constantinople by Greco-Roman Nikaean forces in 1261, the revived Empire of the Romans under the Palaiologos dynasty (this second Roman Empire essentially being a Greek kingdom) had its flag updated to the more recognizeable edition with the four B’s. This B flag design was also found dating to the early pre-Sack 1200’s, meaning that perhaps someone during the reign of the Angelos dynasty was already making designs for the future adopted flag.
