Land issues and predominantly Jewish presence among estate leaseholders accounted for the 1907 Romanian Peasants' Revolt, partly antisemitic in message. During the same period, the anti-Jewish message first expanded beyond its National Liberal base (where it was soon an insignificant attitude), to cover the succession of more radical and Moldavian-based organizations founded by A.C. Cuza (his Democratic Nationalist Party, created in 1910, had the first antisemitic program in Romanian political history). No longer present in the PNL's ideology by the 1920s, antisemitism also tended to surface in on the left-wing of the political spectrum, in currents originating in "Poporanism" - which favoured the claim that peasants were being systematically exploited by Jews.
