Bnei Brak
Beginning in the 1960s, the rebbes of the Ukrainian Ruzhin dynasty (Sadigura, Husiatyn, Bohush), who had formerly lived in Tel Aviv, moved to Bnei Brak. In the 1990s, they were followed by the rebbe of Modzhitz. Unlike the former four Gerrer rebbes, who lived in Jerusalem, the current rebbe was a Bnei Brak resident until 2012. The rebbes of Alexander, Biala-Bnei-Brak, Koidenov, Machnovke, Nadvorne, Premishlan, Radzin, Shomer Emunim. Slonim-Schwarze, Strykov, Tchernobil, Trisk-Bnei-Brak and Zutshke reside in Bnei Brak. Rabbi Moshe Yehuda Leib Landau was the Rabbi of Bnei Brak until his death on March 30, 2019. He was a respected authority on Jewish law and kashrut supervision. The "Rav Landau" hechsher (kosher supervision) is widely accepted. Rabbi Nissim Karelitz, chief Rabbi ("av beis din") of the Lithuanian Haredi community, heads a beth din of Lithuanian and Hasidic dayanim, called "She'eris Yisroel".
