The Outcasts

Because they were carrying customs and memories connected to their Hindu gods, the Roma were regarded as heathens in Byzantium and were assimilated into a heretic sect: "the Untouchables" or Atsingani. This designation is the root of the words used for "Gypsy" in most European languages, such as the French "Tzigane" and the German "Zigeuner". (Roma History)

Roma have worked as coppersmiths possibly since the "Persian period"
They worked on the land or as craftsmen but in two Romanian principalities, Wallachia and Moldova, they were pushed into slavery and feature prominently in property deeds. At this time, the Roma fled towards Ukraine and Russia, where they were given aid or shelter. This welcoming attitude changed dramatically around the year 1500.

Historians believe this might have happened because the numbers of the immigrants grew bigger, but they also were seen as spies for the Turks, and consequently hunted and killed by decree. This led to what some historians dub "the first Roma genocide" - a period of fierce repression. There were hangings and expulsions in England; branding and the shaving of heads in France; severing of the left ear of Roma women in Moravia, and of the right one in Bohemia. Following these expulsions and killings, large groups of Roma travelled back East, towards Poland, which was more tolerant. Russia was also a place where the Roma were treated less heavy-handedly, notably being allowed to retain nomadic or semi-nomadic ways of living, as long as they paid the annual taxes - the "obrok".
