English: The oldest known description of a flag of Serbia is from the 1281 description of a flag in the treasury of King Stefan Vladislav (1233-1243), which was kept in the Dubrovnik Republic. The description lists "vexillum unum de zendato rubeo et blavo" - a flag of fabric red and blue (zendato - čenda a type of light, silky fabric).^[1] We however don't know how were the colours patterned; horizontal diband shown to the left is sometimes used in commemorations of medieval events in Serbia.^[2] As Vladislav ruled from 1233 to 1243 and died after 1264, the flag predates the time of the description, hence making it likely to have been used around the middle XIII century.
