The Blue Horde (Mongolian: Хөх орд; Tatar: Күк Урда/Kük Urda; Turkish: Gök Ordu) was a crucial component of the Mongol Empire established after Genghis Khan's demise in 1227. Functioning as the western part of the split Golden Horde, it contrasted with the White Horde's eastern segment (see the Turkic cardinal system), adhering to the Mongolian and Turkic tradition of cardinal direction colors.
