This new uprising was finally ended by the Treaty of Szatmár, which stipulated that the suppression of all autonomy for the Cumans and Jazyges; the decision was then upheld by the Hungarian Diet. Medievalists Nora Berend and Kyra Lyublyanovics both argue that dissatisfaction with Habsburg centralism reinforced ethnic separatism and contributed to the brief reemergence of a Cuman ethnos; a forged version of the "Cuman laws" of 1279 was produced in the 18th century to justify ancient liberties against normative pressures. Other scholars believe that the document is a reasonably faithful copy of King Ladislaus' writ, with only some modifications.
