What is "tngri"

In the pantheon of Mongolian shamanism, tngri (also tengri, tegri) constitute the highest class of divinities and are attested in sources going back to the thirteenth century. Their name deriving from an earlier Turkic deity, Tengri, they are led by different chief deities in different documents and are divided into a number of different groups—including black (terrifying) and white (benevolent), and eastern and western. While there generally seem to be 99 tngri, some documents propose three others (from the north), and while they are generally the highest divinities, some liturgical texts propose an additional group of 33 chief gods alongside the tngri. They were invoked only by the highest shamans and leaders for special occasions; they continue to be venerated especially in black shamanism. Chief among the tngri are Qormusata Tngri and (Khan) Möngke Tngri.
