From The Crimean War: A History, by Orlando Figes (Metropolitan, 2011), Kindle Loc. 7351-7390:
To encourage the Christian settlement of the Crimea, the tsarist government introduced a law in 1862 granting special rights and subsidies to colonists from Russia and abroad. Land abandoned by the Tatars was set aside for sale to foreigners. The influx of new Christian populations during the 1860s and 1870s transformed the ethnic profile of the Crimea. What had once been Tatar settlements were now populated by Russians, Greeks, Armenians, Bulgarians, even Germans and Estonians – all of them attracted by promises of cheap and fertile land or by special rights of entry into urban guilds and corporations not ordinarily available to newcomers. Armenians and Greeks turned Sevastopol and Evpatoria into major trading centres, while older Tatar towns like Kefe (Theodosia), Gözleve and Bakhchiserai fell into decline. Many of the rural immigrants were Bulgarian or other Christian refugees from Bessarabia, territory ceded by the Russians to the Turks after the Crimean War. They were settled by the government in 330 villages once occupied by the Tatars, and were helped financially to transform mosques into churches. Meanwhile, many of the Tatars who had fled from the Crimea were resettled on the lands abandoned by the Christians in Bessarabia.
All around the Black Sea rim, the Crimean War resulted in the uprooting and transmigration of ethnic and religious groups. They crossed in both directions over the religious line separating Russia from the Muslim world. Greeks emigrated in their tens of thousands from Moldavia and Bessarabia to southern Russia after the Crimean War. Moving in the opposite direction, from Russia into Turkey, were tens of thousands of Polish refugees and soldiers who had fought in the Polish Legion (the so-called ‘Ottoman Cossacks’) against Russia in the Crimea and the Caucasus. They were settled by the Porte on Turkish lands in the Dobrudja region of the Danube delta, in Anatolia and other areas, while others ended up in Adampol (Polonezkoi), the Polish settlement established by Adam Czartoryski, the leader of the Polish emigration, on the outskirts of Constantinople in 1842.
On the other side of the Black Sea, tens of thousands of Christian Armenians left their homes in Anatolia and emigrated to Russian-controlled Transcaucasia in the wake of the Crimean War. They were fearful that the Turks would see them as allies of the Russians and carry out reprisals against them. The European commission appointed by the Paris Treaty to fix the Russian-Ottoman border found Armenian villages ‘half inhabited’ and churches in a state of ‘advanced decay’.
Meanwhile, even larger numbers of Circassians, Abkhazians and other Muslim tribes were forced out of their homelands by the Russians, who after the Crimean War stepped up their military campaign against Shamil, engaging in a concerted policy of what today would be defined as ‘ethnic cleansing’ to Christianize the Caucasus. The campaign was largely driven by the strategic demands created by the Paris settlement in the Black Sea, where the Royal Navy could freely operate and the Russians had no means of self-defence in their vulnerable coastal areas where the Muslim population was hostile to Russia. The Russians focused first on the fertile lands of Circassia in the western Caucasus – territories close to the Black Sea coast. Muslim villages were attacked by Russian troops, men and women massacred, farms and homes destroyed to force the villagers to leave or starve. The Circassians were presented with the choice of moving north to the Kuban plains – far enough away from the coastal areas for them not to be a threat in case of an invasion – or emigrating to the Ottoman Empire. Tens of thousands resettled in the north but equally large numbers of Circassians were herded by the Russians to the Black Sea ports, where, sometimes after weeks of waiting by the docks in terrible conditions, they were loaded onto Turkish boats and taken off to Trebizond, Samsun and Sinope in Anatolia. The Ottoman authorities were unprepared for the mass influx of refugees and several thousands of them died from disease within months of their arrival in Turkey. By 1864 the Muslim population of Circassia had been entirely cleared. The British consul C. H. Dickson claimed that one could walk a whole day in formerly Circassian territories and not meet a living soul.
After the Circassians, it was the turn of the Abkhazian Muslims, at that time settled in the Sukhumi – Kale region, where the Russian campaign to clear them off their lands began in 1866. The tactics were essentially the same as those employed against the Circassians, except this time the Russians had a policy of keeping back the able-bodied male workers out of fear for the economy, and forcing out their women, children and the elderly. The British consul and Arabic scholar William Gifford Palgrave, who made a tour of Abkhazia to collect information on the ethnic cleansing, estimated that three-quarters of the Muslim population had been forced to emigrate. Overall, counting both Circassians and Abkhazians, around 1.2 million Muslims were expelled from the Caucasus in the decade following the Crimean War, most of them resettling in the Ottoman Empire, and by the end of the nineteenth century the Muslims of these two regions were outnumbered by new Christian settlers by more than ten to one.
