Answer
Gaudiya Vaishnavism regains its momentum from 1966 to the present. In the early 20th century, Gaudiya Vaishnavism was mainly a regional movement in Bengal. But with the arrival of Srila Prabhupada in the West in 1966, Gaudiya Vaishnavism began to spread to the rest of the world. Prabhupada's books, lectures, and travels helped to introduce Gaudiya Vaishnavism to people of all cultures and backgrounds.
