Historical Vishnuism as early worship of the deity Vishnu is one of the historical components, branches or origins of the contemporary and early Vaishnavism, which was subject of considerable study, and often showing that Vishnuism is a distinctive worship — a sect. The tradition was forming in the context of Puranic Vaisnavism evolving in the process of revitalizing religion of Brahmanism, of which Vishnuism is believed to be a part, through assimilating a number of orthodox, non-conformist and tribal elements; the absorption of mother goddess worship, into what now known a Vaishnava sampradayas. It is a tradition of the historical Vedic religion and is distinguished from other historic schools later forming the Vaishnavism by its primary worship of Vishnu, later identified as the source of all Avatars. A number of separate sects or traditions merged with each representing the names of god of Vaishnavism. In contemporary Vaishnavism God is also known as Narayana, Vasudeva and Krishna and behind each of those names is a divine figure with attributed supremacy in Vaishnavism, that relates to historic traditions that some scholars theorize to be separate and distinct historically. It is distinct from Krishnaism, as in the revival of Bhakti, found in the Bhagavata it is referred as Vishnuism.
