Once over 3,500 strong, there are only 21 Jews left in Calcutta, India - a city of 14 million people. Despite the fact that in a few years the entire community will disappear, the best hope for keeping the memory of Calcutta's Jews lies (surprisingly) with the Muslim caretakers of the synagogues and the Muslim students who attend the Jewish schools. The Jews in Calcutta never faced anti-Semitism (most immigrated to Britain, Australia, the United States or Israel after India's independence in 1947), and in fact, they have more than once been referred to as a Diaspora of Hope.
