One exception to this is that the most common surnames among Polska Roma are characteristically Polish (for example Kwiatkowski or Majewski), or occasionally Polonized-German (for example Wajs or Szwarc).
Polska Roma generally have had a very strict interpretation of Romanipen cultural laws and practices.
Additional anti-Roma laws were passed in Poland and Lithuania when Augustus the Strong, the Elector of Saxony, was elected king of Poland in 1697.
Saxony, like most German states of the time had very strong anti-Roma legislation (Roma men were to be killed on sight, often with a bounty paid for their ears, while Roma women and children were disfigured, branded and banished) and upon Augustus' inauguration some of these laws were transferred to the Commonwealth.
They have not assimilated into broader Polish society, or the non-Romani cultures of other countries where they live.
Get noticed for who you are, not what you look like.
Their version of the Roma dialect has also incorporated many German words and idioms.
