Then in the resistance movement in Vardar Macedonia were clearly visible two political tendencies. The first one was represented by Tempo and the newly established Macedonian Communist Party, gave priority to battling against any form of manifest or latent pro-Bulgarian sentiment and to bringing the region into the new projected Communist Yugoslav Federation. Veterans of the pro-Bulgarian IMRO and IMRO (United) who had accepted the solution of the Macedonian question as an ethnic preference, now regarded the main objective as being the unification of Macedonia into a single state, whose postwar future was to involve not necessarily inclusion in a Yugoslav federation. They foresaw in it a new form of Serbian dominance over North Macedonia, and prefer rather membership of a Balkan federation or else independence. These two tendencies would have struck in the next few years. In Spring of 1944 the Macedonian National Liberation Army launched an operation called "The Spring Offensive" engaging German and Bulgarian Armies, which had over 60,000 military and administrative personnel in the area. In Strumica, approximately 3,800 fighters took part in the formation of military movements of the region; The 4th, 14th and 20th Macedonian Action Brigades, the Strumica Partisan Detachment and the 50th and 51st Macedonian Divisions were formed. Since the formation of an army in 1943, Macedonian Communist partisans were aspiring to create an autonomous government.
