Migrations to the district included hundreds of Romanies, although the authorities of Jazygia resisted government orders to settle them in as "new Hungarians". Among the new arrivals to the region were new groups of Greeks (many of whom were presumably Aromanian) who set up Orthodox parish churches in Karcag and Kecskemét. These institutions were at the center of disputes between the Ecumenical Patriarchate and the Eparchy of Buda. At Kiskunlacháza, the population remained Cuman and Catholic, while the adjacent (and later incorporated) village of Pereg was reestablished ca. 1750 by Hungarians and Slovaks, who were Calvinists.
