Between the two world wars, some 3,000 Jews lived in the city, constituting roughly a quarter of its residents. In 1918, the first Jewish gymnasium was established. The community had a beit midrash, mikvaot, synagogues, a few prayer halls (such as "Hevra Tehilim"), active youth movements, a library, a Jewish elementary school and a Jewish high school. During this period, movements such as Agudat Yisrael, Beitar, and other Zionist parties, and the Bund were active there. The majority of Jews in Konin were Mitnagdim, though two small communities of Hasidim lived within the Konin Jewish community, mostly adherents of Gerer Hasidism, with a small group of Aleksander Hasidim.
