 At this stage, the collapse of Austria-Hungary had ensured the union of Transylvania with Romania; it also sparked a Hungarian–Romanian War, in which Romania faced a Hungarian Soviet Republic.According to Comnen's own account, he met with a deputation of Hungarian conservatives and liberals, including Count Andrássy, Alftred Windisch-Grätz and Mihály Károlyi, who demanded that Romania back their anti-communist government, based in Szeged, and provide support to the "White Guards".In August 1919, Comnen was contacted by another delegation, representing the Hungarian Republic.
