Such is the Slav Macedonian distrust of the Greek that even the KKE[Communist Party of Greece] is suspect.... KKE may be communist, but
in the eyes of the Slav Macedonian it is primarily Greek. The development this summer of KKM [Communist Party of Macedonia] must offer a prospect of far greater appeal to the Slav-Macedonians in Greece than KKE can provide.
The Macedonians of Aegean or Greek Macedonia made a significant, indeed a critical contribution to the communist side during the Civil War in Greece. They were mobilized for the struggle by their own movement, the National Liberation Front (Naroden Osloboditelen Front, or NOF), which was or sought the role of an autonomous ally and partner, even if a junior one, of the Communist Party of Greece, Kommounistiko Komma tis Elladas (KKE). The two looked like natural allies. They shared a common ideology, Marxism-Leninism, since the NOF was also a communist organization; they both rejected the status quo and wanted to replace it with a communist people's democracy, and, by the late autumn of 1946, they seemed to agree that this aim could probably be attained only through force of arms. In reality, however, the KKE and NOF were divided by deep-seated mutual distrust and animosity. For the former, the struggle was exclusively ideological and its aim was the seizure of power in Greece. For the latter-without in the least questioning its ideological commitment-it was primarily a national struggle, a battle for the national liberation of the Macedonians in Aegean Macedonia.

 Public Record Office (London), CAB 87/79, XC/AI 61791. Broad (Caserta) to Cab-inet, October 15, 1945, Secret Intelligence Service (SIS), Salonica Bureau. “The Mace-donian Autonomy Movement in North-West Greece: Its Setting and Recent Historv." p. 49. (All British documents cited are found in the Public Record Office [hereafter P.R.O.].) This long report (101 pages) contains some factual inaccuracies, but considering the time and the circumstances in which it was written it provides a most valuable and perceptive assessment of the Macedonian question in Greece. By KKM the authors of the report actually meant the NOF (the Macedonian National Liberation Front).
 “Their [Slav-Macedonians'] relations with KKE are by no means clear: The bulk of them were interested primarily in autonomism rather than communism as such. Although they always tended to assume that the nationalist state [greater Macedonia] would also be communist, this did not necessarily reconcile the respective policies of the Slav- Macedonians and the KKE. KKE was still suspected by many Slav- Macedonians of having Greek nationalist leanings. Ibid., p.25. See also Stojan Kiselinovski, Egejskiot del na Makedonija, 1913-1939 (Skopje, 1990), pp.135-36.
