The International Society for Krishna Consciousness (ISKCON), known colloquially as the Hare Krishna movement, is a Gaudiya Vaishnava religious organization. Its core beliefs are based on traditional Hindu scriptures such as the Srimad Bhāgavatam and the Bhagavad-gita, both of which, according to the traditional Hindu view, date back more than 5,000 years. The distinctive appearance of the movement and its culture come from the Gaudiya Vaishnava tradition, which has had adherents in India since the late 15th century and Western converts since the early 1930s.
