When Astrakhan was conquested in 1556, the small Indian community became part of the Moscow state. In the early 18th century, Peter the Great, the first Russian Emperor, met Astrakhan Hindus and on their request asked the Russian Senate to issue a law for protecting the beliefs of Hindus. This was the first law in Russia to protect foreign religion. In 1971 A.C. Bhaktivedanta Swami Prabhupada, the founder of the International Society for Krishna Consciousness (ISKCON), introduced it to Russia. In 1988, ISKCON was first registered as a religion. Later, it was re-registered in 1998. In the same year, there were 120 Krishna communities in Russia.
