In the territories ceded in 1920, the communal separation of Hungarian Jewry remained legally sanctioned. In Slovakia and Carpathian Ruthenia, the 29 Neolog and 31 Status Quo congregations united to form a single federation in 1926, named "Jeschurun" from 1928. In Yugoslavia, the 70 Neolog communities constituted the majority of the Federation of Jewish Religious Congregations () founded in 1919, together with 38 Sephardi ones; the 12 Orthodox refused to join and formed a union of their own. In Romania, the 23 Neolog communities and 7 of the 11 local Status Quo communities united to form the "Western Rite Union of Transylvania and Banat". In 1922, the Neolog community of Rechnitz was the only one in Burgenland not to join the newly created Association of Autonomous Orthodox Congregations.
