The followers of the rebbes from Aleksander were primarily merchants and artisans, especially from Warsaw, and also in Łódź, where there were approximately 35 houses of prayer and study. There were also "shtiblekh" in numerous other towns, including Bełchatów, Opoczno, and Piotrków. In 1914 his brother Betsalel Yoir (1856–1934) began to serve as a rebbe in Łódź, thus starting a second branch of Alexander. After Shmuel Tsvi's death, the dynasty was continued by his son, Yitzchok Menachem Mendel Dancyger (1880–1943), whose accomplishments included the expansion of religious schools in Łódź and in Aleksander. Unlike many chasidic leaders of that period, he was not interested in politics. During the Second World War, he was in the Warsaw Ghetto. Refusing to leave for the Land of Israel, he died along with his family in Treblinka. Nowadays, the community of chasidim of Aleksander exists mainly in Israel, but there are several synagogues ("shtiblekh") in Boro Park, Monsey, Lakewood, Cleveland, Antwerp, London, Zurich, and Melbourne Australia.
