The worship of the deity Krishna, either in the form of deity Krishna or in the form of Vasudeva, Bala Krishna or Gopala can be traced to as early as the 4th century BC. Worship of Krishna as Svayam Bhagavan, or the supreme being, known as Krishnaism, arose in the Middle Ages in the context of the Bhakti movement. From the 10th century AD, Krishna became a favourite subject in performing arts and regional traditions of devotion developed for forms of Krishna such as Jagannatha in Odisha, Vithoba in Maharashtra and Shrinathji in Rajasthan. Since the 1960s the worship of Krishna has also spread in the Western world and in Africa largely due to the International Society for Krishna Consciousness . Gaudia Math is also a leading proponent of Krishna worship.
