Although the largely Hindu city is well-known for its large Muslim and Christian populations, the Paradesi Jewish community, which is less well-known, is rapidly diminishing.
Kashmiri traders in Islamic garb stand in front of businesses painted with banners saying “Shalom!” in the little neighborhood of Mattancherry in the South Indian city of Cochin. Hindu idols and shawls compete with Jewish stars, menorahs, and mezuzahs for space within.
Even though this multiculturalism may appear weird, the majority-Hindu city is well-known for its large Muslim and Christian populations. Less well known is that the Paradesi (Foreign) Jews, who once populated the neighborhood’s Jew Town section, are a fast-dwindling native Jewish group. There were 250 Jews in the prosperous Jew Town enclave at its peak in the 1950s; most thereafter relocated to newly created Israel. Only six Paradesi Jews survive today, most of whom are in their 80s and only one of whom is of childbearing age.
