In the beginning of the 21st century, new Jewish communities have been established in Mumbai, New Delhi, Bangalore, and other cities in India. The new communities have been established by the Chabad-Lubavitch movement which has sent rabbis to create those communities. The communities serve the religious and social needs of Jewish business people who have immigrated or visiting India, and Jewish backpackers touring India. The largest centre is the Nariman House in Mumbai. There are currently 33 synagogues in India, although many no longer function as such and today vary in their levels of preservation.
