After the First World War there were approximately 1,800 Jews in Mordy - more than half of its population. They were mostly employed in trade and peddling, while a few were tradesmen - mainly tailors and cobblers. The community ran a fund for loans underwritten by The Joint. There were several Hasidic Shtiebels in town, as well as Zionist parties such as the Bund and Agudat Yisrael. There was a Jewish public library and a Jewish culture club.
