Cochin Jews (also known as Malabar Jews or Kochinim, from יהודי קוצ'ין) are the oldest group of Jews in India, with roots that are claimed to date back to the time of King Solomon. The Cochin Jews settled in the Kingdom of Cochin in South India, now part of the state of Kerala. As early as the 12th century, mention is made of the Jews in southern India by Benjamin of Tudela. They are known to have developed Judeo-Malayalam, a dialect of Malayalam language.
Following their expulsion from Iberia in 1492 by the Alhambra Decree, a few families of Sephardi Jews eventually made their way to Cochin in the 16th century. They became known as Paradesi Jews (or Foreign Jews). The European Jews maintained some trade connections to Europe, and their language skills were useful. Although the Sephardim spoke Ladino (i.e., Spanish or Judeo-Spanish), in India they learned Judeo-Malayalam from the Malabar Jews. The two communities retained their ethnic and cultural distinctions. In the late 19th century, a few Arabic-speaking Jews, who became known as Baghdadi, also immigrated to southern India, and joined the Paradesi community.
After India gained its independence in 1947 and Israel was established as a nation, most of the Malabar Jews made Aliyah and emigrated from Kerala to Israel in the mid-1950s.
In contrast, most of the Paradesi Jews (Sephardi in origin) preferred to migrate to Australia and other Commonwealth countries, similar to the choices made by Anglo-Indians.
Most of their synagogues still exist in Kerala, with a few being sold or adapted for other uses.
Among the 8 synagogues that survived till the mid-20th century, only the Paradesi synagogue still has a regular congregation. Today it also attracts tourists as a historic site.
Another synagogue at Ernakulam operates partly as a shop by one of few remaining Cochin Jews. A few synagogues are in ruins and one was even demolished and a two-storeyed house was built in its place.
The synagogue at Chendamangalam (Chennamangalam) was reconstructed in 2006 as Kerala Jews Life Style Museum.
