The Romani originated in India. According to mythology, the country was going through a social restructuring and adopting the strict social hierarchy system of castes. Various groups were not included in these newly formed castes for political and religious reasons, and left at the bottom of the caste system. Three groups made up the majority of the casteless: Thieves, musicians/actors (historically performing arts have had a negative social connotation; take a look at Eastern theatre's history, for example), and magicians whose magic was deemed 'heretical' by the local religion. With life in their once native land now unbearable, these casteless people grouped together, forming bands which migrated originally to the West.
