The city of Salonica has many names: Greek Thessalonike, Roman Thessalonica, Slav Solun, Venetian Saloniccho, Turkish Selanik and Hebrew Slonki. For all these peoples it appeared to be the strategic or commercial key to the Balkans. The city stands close to where the Axios (Vardar) river is crossed by the Via Egnatia before it debouches into the Aegean Sea. The river, which rises deep in the Balkans, brought Slav traders to the annual fair of St Demetrios, patron of Salonica and (through their Salonican evangelists, Sts Cyril and Methodios) of all Slavs, each 26 October. The Egnatian highway runs from the Adriatic coast to Constantinople, so linking Old and New Rome at Salonica.
The Slavs found Salonica was a key which they could not turn. Even the most aggressive of Serbian tsars, Stefan Urosh IV, surnamed Dushan (1331—55), was unable to take the long-desired city of St Demetrios. By contrast its shallow harbour and October fair were not particularly attractive to Italian traders even when they were actually offered its key in 1423. By then Salonica had developed another reputation. As the second city of the Byzantine and (eventually) Ottoman Empire, its relationship with the capital in Constantinople was always uneasy. Even when ruled by a secondary member of the imperial family, it gained a local identity as a sort of city-state of its own, with a recognisable if inchoate local leadership, often headed by its archbishop.
The fourteenth-century urban and peasant uprisings of western Europe were paralleled in Byzantium. In western terms, revolutionary Salonica became a ‘commune’ from 1342 to 1350 .In truth, its urban and artisanal mass was only just critical enough to claim local self-determination behind the great walls of the city, with a still shadowy political ideology called ‘Zealot’. But Salonica did not forget those heady days. Its ‘commune’ was a hardly surprising response to outside pressures: civil war in Byzantium (1341—7), the Ottoman entry into Europe (1345—54) and the threat of Dushan (1345), all compounded by the Black Death (1347—8). Yet in Salonica these years are marked by some of the finest surviving late Byzantine decorated churches and by the career of the last great Father of the Roman Orthodox Church: St Gregory Palamas. Palamas was archbishop of Salonica from 1347 to 1359. His doctrines were confirmed by the Roman Orthodox Church in the next century and remain the vital spiritual ideology of the Slav Orthodox in particular. The essentially mystical theology of Palamas maintained that the unknowable essence of God could be approached by revelation rather than reason, and hence was in direct opposition to the Aristotelian scholasticism of the western Church. On the nearby monastic commune of Mount Athos, Palamism was given expression by Hesychasts — best described as ‘Quietists’ — whose spiritual connections with the political ‘Zealots’ were both obvious and obscure.
The Ottomans first besieged Salonica from 1383 to 1387. Local leadership was divided between its governor, the future Emperor Manuel II Palaiologos, and its archbishop, Isidore Glabas (1380—4, 1386—96). Manuel told his subjects to defy the Turkish ultimatum. On St Demetrios’s Day 1383 Glabas warned his flock to mend their ways, just as St Paul had twice written to the Thessalonians on hope, discipline and premature thoughts of the end of the world. Salonica duly fell in 1387.In 1393 the archbishop ventured back to his see. He found that the world there had not ended. Indeed, Ottoman occupation was more tolerable than Manuel had threatened. Sultan Bayazid had granted the citizens special favours and had left the infrastructure of Byzantine local government and its officers largely in place.
The fact was that the Ottomans could do no other. Vastly outnumbered by the people they conquered, their problem was manpower: there were too few Muslims to go round, and of those too few Turks. The solution was obvious. While the conversion of an Orthodox Christian to Islam could be swift and relatively painless, it takes longer to turn a Roman into a Turk, which is a theme of this chapter. Yet there were short-cuts. In a sermon delivered in occupied Salonica in 1395 Archbishop Glabas was early to report on an expedient which may date from the first substantial Ottoman establishment in Europe, at Gallipoli in the Dardanelles in 1354. It is called devshirme (‘recruitment’) in Turkish and paidomazoma (‘harvest of children’) in Greek. This ‘child levy’ took Christians for training in the Ottoman administration and, especially, in the ‘new army’ (Turkishyeni cheri; English janissary). Girls could aspire to the Harem. It was such converts who were the most eager for further conquest. Their advancement, especially after the battle of Ankara in 1402, led to tension with the old Anatolian Turkish leadership, which was to come to a head in 1453.
In the aftermath of Timur’s victory at Ankara, Salonica reverted to Byzantium in 1403. Once again its archbishop provided characteristic leadership. Archbishop Symeon of Salonica (1416/17—29), urged his flock to keep firmly Roman and Orthodox. An ardent Hesychast, he sought to restore the identity of the city in the face of Venetian and Ottoman pressure. It was difficult to know who constituted the greater threat: the Turks, converts from Orthodoxy included, who were sent to chastise the Salonicans for their sins, or the Venetians who would infect them with the plague of heresy. From St Sophia, Constantinople, Symeon reintroduced a public liturgy to his own cathedral of St Sophia, in Salonica, and, as in Constantinople, regulated a twice-daily street procession of the protecting icon of the Mother of God called the Hodegetria. But in Constantinople Manuel II Palaiologos (1391—1425), by then aged seventy-three, was now more cautious. In 1423, unable to defend Salonica against the Ottomans, the emperor invited the Republic of Venice to do it for him. Archbishop Symeon tried to rally his Roman Orthodox by chastising them in the name of St Demetrios, on whose miraculous defences of the city in the past he wrote a great discourse in Venetian-occupied Salonica in 1427/8. Actually, the Venetians were initially welcomed as no great friends of the pope in Rome, but found the place expensive to defend and the Salonicans doing deals with the Turks. The end really came with Archbishop Symeon’s death late in 1429, which meant that the Ottomans finally took a demoralised city on 29 March 1430. The Venetian captains had slipped away; the icon of the Hodegetria was smashed; and 7,000 Salonicans were taken captive.
What happened next is partly revealed in Ottoman tahrir defters, tax and census registers. Short of manpower, the Ottomans correctly targeted cities such as Salonica, first to Islamicise, and then Turkicise. Outside the walls the overwhelmingly peasant population could await assimilation. Sultan Mehemmed II had a declared policy of demographic manipulation, today called ‘ethnic cleansing’, which has good Byzantine precedent. The Ottoman term was surgun (forcible deportation and resettlement), which, along with devshirme, noted by Glabas, and natural erosion by conversion, should soon have made Salonica the second Ottoman city of the Empire. But this did not happen. The place recovered slowly after 1430, within walls enclosing about 285 hectares, which in medieval Mediterranean terms could encompass a population of 30,000 or more.
In fact Salonica had an adult population of about 10,414 by 1478, which doubled to 20,331 in c. 1500 and only tripled to reach 29,220 by 1519. The precision of Ottoman registers is spurious (for it omits tax-evaders and tax-exempt), but the scale is reliable enough. Clearly, resettlement and conversion were belated. In 1478 the city had a Muslim population of 4,320, but its Christian (Roman Orthodox) element, with 6,094 souls, was still in an absolute majority with 59 per cent of households. By c. 1500 the Christian population had grown to 7,986 but, with 8,575, the Muslim population had doubled to reach, for the first and last time, a simple majority of 42 per cent of the inhabitants of Salonica. But about 1500 a third category was introduced, if incompletely recorded: 3,770 Jews. By 1519, 15,715 Jews were registered: 54 per cent of the population of Salonica, an absolute majority which they maintained until the semi-conversion of many to Islam with that of their false Messiah, Sabbatai Zavi (1625—76) after 1666.
The conversion of the major city of the Balkans, from the staunchly Roman Orthodox see of Archbishops Palamas, Glabas and Symeon, first into a Muslim stronghold and then into the largest Jewish city in the world, all within the space of four decades, needs explanation. In the past, Byzantine emperors had in turn invited western Christian powers and Ottoman Turks to fight their wars against Orthodox Serbs and Bulgars for them, and regretted the expedient. Now the Ottoman state was faced with a greater, demographic, war. If Salonica could not be turned Turk, a third urban element could be introduced. Before 1430 there is evidence for a few Greek-speaking and Karaite Jews in the city, not even registered in 1478. But after their conquest of Granada in 1492, the Catholic sovereigns, Ferdinand and Isabel, expelled their Spanish (Sephardic) Jews, who spoke Ladino (or ‘Latin’). Bayazid II welcomed them through Constantinople, largely to settle in Salonica. It was the greatest surgun of all. Ottoman demographic strategy, if such it was, meant that Salonica did not have a Roman Orthodox majority again until after 1912, when it fell to Greece, once more to become a second city.
