Zambrów

Zambrów lies on the Jabłonka in northeastern Mazovia. A possession of the Piast dukes, it appears in records from 1283 and received town rights under Chełmno law in 1430. Duke Janusz II established two annual fairs in 1479, and three more followed in 1523. These markets and the brewing trade helped the royal town prosper in the fifteenth and sixteenth centuries. The Swedish invasion in the mid-seventeenth century destroyed much of Zambrów and brought its period of prosperity to an end.
