Hello dear ,

As per my knowledge ,Jangam is a sub-caste of the Veerashaiva community called [Veerashaivism religion] under Hinduism. Veerashaiva and Lingayat ways of life are different. Their beliefs, practices and faith are different. Veerashaiva worship Lord Shiva, the one mentioned in Hindu mythology. In terms of religious practice, Basavanna propagated only the worship of Ishta Linga.

Hope this helps !!
