English: The flag of the Golden Horde, as shown in Angelino Dulcert's 1339 map. A similar flag appears in the later Catalan Atlas (1375), providing corroboration.

One of the charges is a crescent and the other looks like a simplified form of the tamga from the flag of Idel Ural. On different copies of the flag, the crescent has different size; it is often smaller than shown here, sometimes even reduced into a simple oblique stroke and conjoined with the other charge into a si[n]gle symmetrical object; the other charge also sometimes lacks the oblique part [2, 3]. It was obviously difficult to draw the charges always the same way. The cities with this flag which are easy to identify are [2, 7, 8]: Sarai, the capital (spelled Sarra) - there is also a depiction of the ruler, "Jani Beg Lord of Sarai" ("Jambech senyor de Sarra"); Tana, present-day Azov, Russia; and Urgench, Uzbekistan (spelled Organci, with a cedilla under the c; nowadays ruined). This flag is a variant of the flag of "Emperor of Sarai" ("Emperador de Sara") from "Libro del conoscimiento de los reinos" [7] and might be the one that had really existed, considering the similarity of its charges with those from the flag of Idel Ural.
