In the 1930s, Pabongkhapa Déchen Nyingpo started to promote "Dorje Shugden". According to Kay, Pabongka fashioned Shugden as a violent protector of the Gelug school, who is employed against other traditions, transforming Dorje Shugden's "marginal practice into a central element of the Ge-luk tradition", thus "replacing the traditional supra-mundane protectors of the Ge-luk tradition", namely Mahākāla, Kalarupa, Vaiśravaṇa, Palden Lhamo, Pehar and Nechung who were appointed by Je Tsongkhapa.
