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. Comprising István Bethlen, Miklós Bánffy, and Pál Teleki, it asked for Transylvania to be recognized as a federal entity of the Romanian state.
