There is a recurring motif in certain strands of Serbian irredentist and nationalist rhetoric: the dream of restoring Constantinople—today’s Istanbul—to “Orthodox rule.” The language is often elevated and religious. It frames the city as a sacred center of Orthodoxy that must one day be liberated from Ottoman/Turkish control and returned to its proper Christian stewardship. Yet the practical and political implication is rarely “Orthodox rule” in any abstract or pan-Orthodox sense. It is Serbian, or at least Slavic, rule—an extension of national ambition draped in the language of faith. That is the central irony.
Constantinople has no origin in Serbia or among the Slavs. It was founded by the Roman emperor Constantine the Great, who was from Nissus – prior to Slavs or Serbs – in 330 CE as the new imperial capital on the site of ancient Byzantium. For more than a thousand years it served as the political, cultural, and ecclesiastical heart of the Eastern Roman (Byzantine) Empire. Its language of administration and high culture was Greek; its church was the Ecumenical Patriarchate, the “Mother Church” of Eastern Orthodoxy. The city was never a Slavic foundation, never a Serbian capital, and never the seat of a specifically Slavic form of Christianity.
The reverse is true: Slavic Orthodoxy derives from Constantinople. Missionaries operating under Byzantine auspices—most famously Cyril and Methodius in the ninth century—brought Christianity, the Glagolitic and later Cyrillic scripts, and liturgical traditions to the Slavs. The conversion of the Serbs, like that of the Bulgarians, Russians, and others, was a downstream event.
The Serbian Orthodox Church looked to Constantinople as the source. Medieval Serbian rulers, including the Nemanjić dynasty, operated in the Byzantine cultural and political orbit. They built churches in the Byzantine style, married into Byzantine families, and adopted Byzantine titles and administrative practices.
Stefan Dušan went furthest: in the mid-fourteenth century he crowned himself “Emperor of the Serbs and Romans” (or “of Serbia and Romania”), explicitly claiming a share of the Byzantine imperial inheritance and eyeing further expansion that could have threatened Constantinople itself. His empire was powerful and expansionist within the Balkans, but it never took the city, and after his death it fragmented. The Ottomans completed the conquest of Constantinople in 1453.
When modern Serbian irredentist accounts speak of “liberating” Constantinople for Orthodoxy, they are therefore reversing the historical relationship. They treat the source as if it were a lost possession of the recipient. The sacral language—Orthodox restoration, return of the Queen of Cities to Christian hands—functions as a cloak.
What it conceals, or sometimes barely conceals, is an imperial vision in which Serbian or broader South Slavic power would somehow extend to the Bosporus. In the logic of such rhetoric, the city becomes not merely a religious symbol but a territorial endpoint of national grandeur. Serbia (or a Greater Serbia) reaching Istanbul is the unspoken geographic claim.
That is textbook imperialism: the projection of national power over lands and peoples that have never been Serbian, justified by a selective reading of medieval imperial pretensions and a romanticized Byzantine inheritance.
This is not unique to Serbian nationalism. Greek irredentism long entertained the Megali Idea, which explicitly included Constantinople. Russian messianism after 1453 developed the “Third Rome” doctrine and periodic fantasies of reclaiming the city. Far-right online spaces across Orthodox countries recycle memes about retaking Hagia Sophia and Constantinople. In the Serbian case, the motif appears in certain nationalist cultural productions, historical romanticism around “Serbian Byzantium,” and fringe activist discourse that blends Kosovo mythology, medieval imperial memory, and anti-Turkish sentiment.
Greater Serbia ideology has traditionally focused on the western and southern Balkans—Bosnia, Croatia, Montenegro, Macedonia, Kosovo—rather than a literal march to the Golden Horn. Yet the symbolic elevation of Constantinople still serves a useful function: it elevates local territorial claims into a civilizational, almost eschatological register. Local expansion is thereby sacralized as the recovery of a universal Orthodox order that, in practice, would be administered under Serbian auspices.
The irony deepens when one considers demography, history, and theology. Constantinople’s Orthodox community has for centuries been predominantly Greek (with smaller Armenian, Arab, and other components). The Ecumenical Patriarchate remains the first among equals in the Orthodox world precisely because of its continuity with the imperial see, not because of any Slavic inheritance. Serbian Orthodoxy is autocephalous and fully legitimate; it does not need to possess the city to validate itself.
Treating the city as a future Serbian prize confuses the universal claims of Orthodoxy with the particular claims of one nation. It also ignores the reality that any serious attempt to “liberate” Istanbul would require conquering a major Turkish metropolis of some 15–16 million people, most of them Muslim, in a NATO member state. The gap between the sacral rhetoric and the geopolitical absurdity is vast.
None of this denies the real historical connections. Serbs lived, traded, fought, and built in and around the Byzantine world. Some Serbian rulers and nobles left material traces in Constantinople. The trauma of Ottoman rule and the Battle of Kosovo remain central to Serbian historical memory.
Medieval Serbia was a small Balkan power that briefly challenged Byzantine residual strength. Acknowledging those facts does not require accepting the leap from “we participated in the Byzantine cultural sphere” to “Constantinople rightfully belongs under Serbian Slavic rule.” The latter is not restoration; it is appropriation.
Irredentist discourse that cloaks national expansion in the language of Orthodox liberation performs a familiar ideological maneuver: it turns a particular ethnic or state ambition into a sacred duty. In the Serbian case, the maneuver is especially ironic because the city being claimed is the very place from which the claimants’ own religious tradition originally flowed.
Constantinople was never Serbian by origin. Slavic Orthodoxy is not its source but its heir. When activists invoke the “liberation” of the city, they are not recovering a lost Serbian patrimony. They are dressing imperial aspiration in the vestments of a faith that, historically, ran in the opposite direction.
