The great majority of India’s population are adherents of Hinduism, a religion whose history stretches back thousands of years. Hinduism is very tolerant of other religions, due mainly to a tendency to regard the gods of other religions as being variant manifestations of Hindu gods. Such tolerance allowed Jewish communities to be established and remain in India for centuries. However, the majority of Jews left India after the establishment of the State of Israel in 1947; the majority settled in Israel, but significant numbers also moved to countries such as Australia.
