The black and white jews in Kerela

Before his death, Moses bequeathed command of the twelve tribes of his people to Joshua, who went on to conquer the land of Canaan around 1200 BCE, according to the Bible. The land was eventually divided between these tribes. Judah and Benjamin took the southern territories, which would become the Kingdom of Judah, while the remaining ten tribes took the land which would become the Kingdom of Israel. In 722 BCE Israel fell to the Assyrians and its people were dispersed.The Bible maintains that the Jews safeguarded their religious identity in fooreign lands and prophesies that one day they would be reunited in the Holy Land. the story of the Lost Tribes remains an inviolable belief for many jews. It ensnared the imagination of chroniclers, with accounts of communities that survived despite their displacement in alien lands. It has been suggested that the Jews or India are among the Lost Tribes, alongside the Folasha of Ethiopia and Pathans of Afghanistan.

Bene Israel Jews are the largest community of Jews in india at around 5000.
