Bhaktisiddhanta Sarasvati
The revival of Gaudiya Vaishnavism effected by Bhaktivinoda spawned one of India's most dynamic preaching missions of the early 20th century, the Gaudiya Matha, headed by his son and spiritual heir, Bhaktisiddhanta Sarasvati. Bhaktisiddhanta's disciple A.C. Bhaktivedanta Swami (1896–1977) continued his "guru" Western mission when in 1966 in the United States he founded ISKCON, or the Hare Krishna movement, which then spread Gaudiya Vaishnavism globally.
