Category:Flags of the Mongol Empire
Often the only source is the Catalan Atlas, which as a historical primary source cannot be considered a reliable reference. Those flags should not be added to articles about the Mongol Empire. If they are added anyway, then their speculative nature must be clearly indicated.The main "modern" source is often "Flags of the World" (fotw). Note that fotw is based on user contributions like Wikipedia, and hence not authoritative either.
