Introduction
On the eastern shore of the Adriatic Sea, where limestone mountains descend toward a restless blue horizon, lies the city of Split – a place where history is not confined to museums or footnotes but embedded in walls, courtyards, streets, and daily routines. Few European cities possess such an unbroken continuity of life within a structure originally conceived for imperial retreat. Split is not merely old; it is cumulative. Every era has left something behind, not by erasing the past, but by adapting it.
Before the City: Geography, Illyrians, and the Roman World
Long before Split emerged as a recognizable urban entity, the central Dalmatian coast was already a zone of movement and encounter. Sheltered bays, fertile hinterlands, and island chains made the area attractive to prehistoric communities and later to Illyrian tribes. These early inhabitants left limited written evidence, but archaeological traces suggest a network of hillforts and coastal settlements oriented toward both land and sea.
The decisive transformation came with Roman expansion into the eastern Adriatic. By the first century BCE, Roman authority had been established, reorganizing the region into the province of Dalmatia. Nearby Salona became the provincial capital, a flourishing urban center with forums, amphitheaters, aqueducts, and a population that may have reached 60,000 at its height. Salona’s prosperity mattered profoundly for the later rise of Split, even though the two sites had distinct roles.
While Salona functioned as an administrative and commercial hub, the area that would become Split remained largely peripheral—coastal land suitable for villas, agriculture, and retreat rather than governance. This distinction explains why Split did not begin as a city at all, but as something more personal, more imperial, and ultimately more adaptable.
An Emperor’s Retirement: The Creation of Diocletian’s Palace
The foundational moment in Split’s history occurred at the turn of the fourth century CE, when the Roman emperor Diocletian chose this stretch of Dalmatian coast as the site for his retirement residence. Having ruled a vast and unstable empire, Diocletian was the first Roman emperor to abdicate voluntarily. His decision to build a massive palace near Salona was both practical and symbolic: practical because of the region’s climate and loyalty, symbolic because it fused imperial authority with personal withdrawal.
The result was Diocletian’s Palace, constructed between approximately 295 and 305 CE. Neither purely a villa nor simply a fortress, the palace combined elements of military camp, imperial residence, and ceremonial complex. Rectangular in plan and enclosed by massive stone walls with towers, it was divided into quadrants by two main streets, echoing Roman urban design. Within its southern section stood the emperor’s private apartments overlooking the sea, while the northern areas housed soldiers, servants, and storage.
At its heart lay monumental spaces: the peristyle courtyard, the mausoleum (later a cathedral), and temples dedicated to Roman gods. Built of local limestone and marble imported from across the Mediterranean, the palace embodied both Dalmatian craftsmanship and imperial reach. At the time of its completion, however, no one could have predicted that this “retirement home” would become the nucleus of a city still thriving more than seventeen centuries later.
Collapse and Continuity: From Roman Palace to Refuge City
The survival of Split is inseparable from the destruction of Salona. In the sixth and seventh centuries, waves of invasions and migrations—often associated with Avars and Slavic groups—devastated Roman urban centers along the Adriatic hinterland. Salona was abandoned, its population dispersed or seeking refuge behind stronger defenses.
The palace, with its thick walls and coastal position, offered safety. Refugees from Salona moved into the structure, transforming imperial halls into homes, storage rooms into workshops, and corridors into streets. This moment marks one of the most extraordinary urban adaptations in European history: a palace becoming a city without ever being planned as one.
Rather than erasing Roman architecture, the new inhabitants reused it. Walls were subdivided, columns repurposed, and open courtyards enclosed. The mausoleum of Diocletian, once a symbol of imperial self-glorification, was converted into a Christian cathedral—a powerful act of symbolic inversion, given the emperor’s role in persecuting Christians. The palace’s temples, gates, and substructures acquired new functions that blended sacred, domestic, and commercial life.
By the early Middle Ages, Split had emerged as a distinct urban community, no longer a Roman outpost but not yet a Slavic town in the modern sense. It was a hybrid: Latin in heritage, Christian in identity, and increasingly Slavic in population.
Between Empires: Byzantium, the Papacy, and the Medieval City
Throughout the early medieval period, Split occupied a delicate geopolitical position. Formally, it remained under the influence of the Eastern Roman—or Byzantine Empire—which claimed authority over the Dalmatian coast long after losing much of the Balkan interior. In practice, however, local elites exercised considerable autonomy, navigating between imperial claims, papal authority, and emerging Slavic polities.
Split became a bishopric and later an archbishopric, strengthening its religious and cultural importance. Latin liturgy and Roman legal traditions persisted, even as Slavic language and customs gained ground. The city was not isolated; it maintained maritime connections with Italy and the wider Mediterranean, acting as a conduit between different cultural worlds.
Medieval Split developed beyond the palace walls, though the ancient structure remained its core. New houses rose atop Roman foundations, and medieval streets followed paths dictated by ancient corridors. Communal institutions emerged: city councils, guilds, and statutes regulating trade, property, and public behavior. The city’s identity was increasingly urban and civic, defined by local rights rather than imperial patronage.
Yet this autonomy was always precarious. Powerful neighbors—Croatian kings, Byzantine governors, and later Venetian merchants—sought influence over the strategically valuable Dalmatian coast. Split’s history during this period is one of negotiation rather than conquest, survival through flexibility rather than force.
Under the Lion’s Wing: Venetian Rule and Maritime Identity
From the late Middle Ages until the end of the eighteenth century, Split was part of the maritime empire of Republic of Venice. Venetian rule brought both stability and constraint. On one hand, inclusion in Venice’s trading network ensured protection from piracy and integration into Adriatic commerce. On the other, political autonomy was curtailed, and economic life was oriented toward Venetian interests.
The imprint of Venice is visible in architecture, law, and urban culture. Gothic and Renaissance elements appeared alongside Roman and medieval structures, adding new stylistic layers to the cityscape. Palaces, loggias, and public buildings reflected Venetian tastes, while Latin remained the language of administration.
Split’s economy during this period relied on maritime trade, shipbuilding, and its role as an intermediary between the coast and the Balkan interior. The city also stood on the frontier with the Ottoman Empire, whose expansion into the Balkans reshaped regional dynamics. While Split was never conquered, the Ottoman presence influenced trade routes, demographics, and security concerns.
Life under Venice was not static. Periods of prosperity alternated with hardship caused by war, plague, and economic shifts. Yet through it all, Split retained its urban character, grounded in civic institutions and a strong sense of local identity rooted in its unique physical environment.
Enlightenment and Empire: The Habsburg and Napoleonic Interlude
The fall of the Venetian Republic in 1797 marked a turning point. Dalmatia, including Split, passed through a brief and turbulent succession of rulers. The city experienced French administration during the Napoleonic era, followed by incorporation into the Austro-Hungarian Empire.
These transitions brought new ideas about governance, infrastructure, and identity. Enlightenment principles influenced legal reforms, while modern bureaucracy replaced older communal systems. Roads, ports, and public services were improved, connecting Split more closely to its hinterland and to Central Europe.
Culturally, the nineteenth century was a period of awakening. National movements among Croats and other South Slavs gained momentum, challenging older imperial identities. In Split, debates over language, education, and political loyalty reflected broader struggles between Italian-speaking elites and Slavic-speaking populations. Newspapers, societies, and schools became arenas for defining what the city—and the nation—should become.
Despite political tensions, the city grew. New neighborhoods emerged beyond the ancient core, while the palace continued to serve as a lived-in center rather than a preserved relic. This coexistence of ancient and modern would become one of Split’s defining characteristics.
War, Kingdom, and Socialism: The Twentieth Century
The twentieth century brought upheavals that reshaped Split profoundly. The collapse of Austro-Hungary after the First World War led to the city’s inclusion in the Kingdom of Yugoslavia, marking a decisive shift toward a South Slavic political framework. These years were marked by economic challenges, migration, and ongoing cultural negotiations.
The Second World War was particularly traumatic. Occupation, resistance, and bombardment left scars on the city and its population. Many citizens joined partisan movements, and Split emerged from the war aligned with the new socialist state of Yugoslavia.
Under socialism, Split underwent rapid industrialization and urban expansion. Shipyards, factories, and housing projects transformed it from a compact coastal town into a major regional center. Education, sports, and culture were promoted as expressions of collective identity. At the same time, historic preservation was uneven; while the palace survived, other parts of the old city faced neglect or insensitive development.
Yet even during this period of modernization, Split’s past remained visible and influential. The palace was not emptied or sanitized; it continued to house families, shops, and cafes. This continuity distinguished Split from many historic cities where old centers became museums disconnected from everyday life.
Independence and Reinvention: Split in Contemporary Croatia
The dissolution of Yugoslavia in the early 1990s and the emergence of independent Croatia brought another chapter of uncertainty and change. The Homeland War affected Split indirectly through refugees, economic disruption, and political transformation. However, the city avoided large-scale physical destruction and soon entered a phase of recovery.
In the decades since independence, Split has reinvented itself as a cultural, educational, and tourist hub. Tourism, in particular, has become a dominant force, drawing visitors to the palace, the waterfront, and nearby islands. This influx has generated wealth but also raised questions about sustainability, housing, and the balance between local life and global demand.
At the same time, there has been a renewed appreciation of heritage. Restoration projects, archaeological research, and cultural festivals highlight Split’s layered history while seeking to integrate it into contemporary urban life. The challenge remains the same as it has been for centuries: how to live within history without being trapped by it.
