Idumeans

Idumeans also known as Red Jews are the descendants of the Idumeans forcibly converted to Judaism by John Hyrcanus around 100BC when he ordered the entire population to be enslaved and then freed. Hence they are also known as Ercolians or Hyrcanian Jews. Although they accept the Mishna they do not have a very sophisticated understanding of Judaism and are comparable to Samaritans, Falashahs and Karaites.
