observers argue that even at this time it was doubtful whether the Slavs from Macedonia considered themselves to be a nationality separate from the Bulgarians." The Macedonian conflict: ethnic nationalism in a transnational world, Loring M. Danforth, Princeton University Press, 1997, , pp. 65–66."Yugoslav Communists recognized the existence of a Macedonian nationality during WWII to quiet fears of the Macedonian population that a communist Yugoslavia would continue to follow the former Yugoslav policy of forced Serbianization. Hence, for them to recognize the inhabitants of Macedonia as Bulgarians would be tantamount to admitting that they should be part of the Bulgarian state. For that the Yugoslav Communists were most anxious to mold Macedonian history to fit their conception of Macedonian consciousness. The treatment of Macedonian history in Communist Yugoslavia had the same primary goal as the creation of the Macedonian language: to de-Bulgarize the Macedonian Slavs and to create a separate national consciousness that would inspire identification with Yugoslavia."

The formerly leading Bulgarian community was reduced either by population exchanges or by change of communities' ethnic identity. The Macedonian Slavs were faced with the policy of forced Serbianisation. Yugoslav agenda 20th-century Serbian and afterwards the Yugoslav historiography used the location of Samuel's state mainly on the territory of then Yugoslavia, to reject Bulgarian claims on the region. Thus, the Russian-born Yugoslavian historian George Ostrogorsky distinguished Samuel's Empire from the Bulgarian Empire, referring to it as a "Macedonian Empire", although he recognised that Samuel's state was politically and ecclesiastically a direct descendant of the empire of Simeon I of Bulgaria and Peter I of Bulgaria, and it was regarded by Samuel and the Byzantines as being the Bulgarian Empire itself. Some historians of the same school, such as the Serbian scholar Dragutin Anastasijević, even claimed that Samuel ruled a separate South Slavic, i.e. Serbian Empire in Macedonia, founded as
