This talk argues that the ethnic conflicts of Southeast Europe are not the result of “ancient hatreds,” but of a specific historical configuration shaped during the Ottoman period. Under Ottoman rule, earlier forms of statehood did not disappear but survived in memory and identity in a kind of “suspended animation,” while at the same time demographic structures were significantly reshaped. Conflict emerged where these two processes intersected. In regions such as Kosovo, Bosnia, Vojvodina, and Transylvania, one group could claim historical precedence based on earlier statehood, while another could claim legitimacy based on later demographic dominance. The Greek–Turkish case shows a similar pattern, where a Byzantine territorial memory and Turkish nationhood collided over territories that became ethnically mixed during the Ottoman rule. The result is a particular type of conflict: not between truth and falsehood, but between competing and internally coherent forms of historical legitimacy — where both sides can plausibly claim that the land is, in different senses, their own.
