Generally speaking, the turn of the year 1918/19 meant further escalations of violence for the Central-Eastern European macro-region. This was caused by three key factors: firstly, the conflicts between the successor states of the Habsburg Empire and the connected battles between the Hungarian Councils and the neighbouring states; secondly, Poland’s territorial claims and those of its antagonists; and thirdly, the advance of the Red Army into the former German-Austrian occupied territories.
