What does it mean to be covered in gold?
Golden tent
Genghis Kahn
The name Golden Horde is said to have been inspired by the golden color of the tents the Mongols lived in during wartime, or an actual golden tent used by Batu Khan or by Uzbek Khan, or to have been bestowed by the Slavic tributaries to describe the great wealth of the khan. But the Mongolic word for the color yellow (Sarı/Saru) also meant "center" or "central" in Old Turkic and Mongolic languages, and "horde" probably comes from the Mongolic word ORDU, meaning palace, camp or headquarters, so "Golden Horde" may simply have come from a Mongolic term for "central camp".
