Between the 16th and 18th centuries, in Mazovia, communities were formed by the Jews living in a city, being the organizational centre of the community (Kahal), and in the nearby cities, towns and villages. Some of the latter had a status as subordinate urban communities [przykahałki]. Other, utterly dependent centres were subordinate to them. Community structures of the Jewish autonomous governments formed districts called „ziemstwo” and at the beginning of the 17th century Mazovian Jewish Communities belonged to Ziemstwo Wielkopolskie. Later, Jewish neighborhoods located on the southern edge of the Mazovian and Rawskie Voivodeships accepted the authority of Ziemstwo Lubelskie. However, Jewish centres located in the north-eastern part of the Mazovian Voivodeship were subordinate directly to kahalas in Tykocin or Węgrów, being in a strong position in the structures of the Jewish autonomous government.
