Book excerpt: Tudor Parfitt examines a myth which is based on one of the world's oldest mysteries - what happened to the lost tribes of Israel? Christians and Jews alike have attached great importance to the legendary fate of these tribes which has had a remarkable impact on their ideologies throughout history. Each tribe of Israel claimed descent from one of the twelve sons of Jacob and the land of Israel was eventually divided up between them. Following a schism which formed after the death of Solomon, ten of the tribes set up an independent northern kingdom, whilst those of Judah and Levi set up a separate southern kingdom. In 721BC the ten northern tribes were ethnically cleansed by the Assyrians and the Bible states they were placed: in Halah and in Habor by the river of Gozan and in the city of Medes. The Bible also foretold that one day they would be reunited with the southern tribes in the final redemption of the people of Israel. Their subsequent history became a tapestry of legend and hearsay. The belief persisted that they had been lost in some remote part of the world and there were countless suggestions and claims as to where.
