In 1864 Russian forces carried out what some have deemed "the first modern genocide on European soil" after they seized the lands of the Circassians -- which include the area around Sochi where Russia staged last year's Winter Olympics.
It's a tense moment for relations between Russia and Turkey. Moscow's intervention into the conflict in Syria, almost explicitly on behalf of the embattled regime of President Bashar al-Assad, has infuriated Ankara, which for years has led international calls for Assad's departure.
The situation grew darker following reports of Russian fighter jets violating Turkish airspace earlier this week. "An attack on Turkey means an attack on NATO," said Turkish President Recep Tayyip Erdogan, whose country possesses the second largest army in the NATO military alliance.
Erdogan warned the Kremlin that its relationship with Turkey was in peril.
"Our positive relationship with Russia is known," he said. "But if Russia loses a friend like Turkey, with whom it has been cooperating on many issues, it will lose a lot, and it should know that."
The thinly veiled warning is a glimpse of the scale of the current crisis. In recent years, the two countries have shared reasonably close ties, anchored inenergy interests. Erdogan's political style, meanwhile, has a great deal in common with that of Russian President Vladimir Putin.
[Why Putin and Erdogan are made for each other]
But there is a long, profound history of unease between Russian and Turkish rulers. During the Cold War, Turkey was a heavily armed NATO bulwark in the shadow of the Soviet empire. And well before the advent of the U.S.S.R. and the modern Turkish republic, the jockeying between Russians and Turks had a huge impact on the political fate of a vast sweep of Europe and the Middle East.
Wars, deportations, and the specter of genocide
In the 18th and 19th centuries, the expansionist Russian empire and the Ottomans fought myriad wars. They largely resulted in Ottoman setbacks, with the Russians wresting control of the northern rim of the Black Sea and chipping away at Ottoman domains in Eastern Europe and the Balkans. The Crimean War, a bloody, brutal conflict in the 1850s, brought in an alliance of European powers in defense of the Ottomans and saw the continent's first chilling encounter with the horrors of large-scale trench warfare.
The rulers of both empires saw themselves as standard bearers of civilizations -- the Ottomans as the seat of Islam, the Russians as the champions of the Orthodox Church and the redeemers, even, of the legacy of the ancient Byzantines. The czars in Moscow coveted Istanbul, and saw in its conquest a pathway to the warm waters of the Mediterranean and suzerainty over the Holy Lands.

That never came to pass, but a lot else did. Russian campaigns in the Caucasus and lands around the Black Sea saw the massacre and mass deportations of populations of Turkic Muslims. In 1864, for example, Russian forces carried out what some have deemed "the first modern genocide on European soil" after they seized the lands of the Circassians -- which include the area around Sochi where Russia staged last year's Winter Olympics.
Tens of thousands of Circassians were systematically butchered; countless others died of starvation or cold as they trekked into exile. Some accounts suggest as many as a million -- half of the ethnic group's total population -- died at the time. Now, up to 5 million Turks claim some form of Circassian or other Caucasian heritage.
It worked in the other direction, as well. Most infamously, as World War I raged, the Ottomans carried out mass deportations and killings of the empire's Armenians, the vast majority of whom lived in what is now central and eastern Turkey. Fearing this community of Christians to be a potential Russian fifth column, Ottoman leaders gave orders for their removal from their homelands.
WorldViews documented the scale of the tragedy that took place beginning in 1915, which saw countless Armenians executed, raped and forced into grim death marches into the desert. Scholars, international organizations and a host of Western governments all believe the atrocities amount to genocide. An estimated 5 million Ottoman civilians perished between 1914 and 1922, casualties of the upheavals that surrounded the empire's implosion.
Hundreds of thousands of Armenians eventually escaped to Russian lands, some settling in what is now modern-day Armenia -- once a part of the Ottoman Empire that, until the 19th century, was largely Muslim.
The birth of nations
In the 19th century, Russia played a prominent role in fomenting nationalism in parts of Eastern Europe and the Balkans once lorded over by the Muslim Ottomans. Russia had a hand in a number of prominent 19th century liberation movements -- from Greece to Serbia to Bulgaria. That was a role that led it into a geopolitical competition with the Austro-Hungarian empire, tensions that would eventually flare into World War I.
The wars that flared in the late 19th century, including the seismic Russo-Turkish war of 1877-1878 and the later Balkan wars that preceded World War I, made clearer the borders of Eastern Europe's future nation-states. It also saw massive population displacements, the exodus of Christian, Jewish, and Muslim refugees in various directions, and the collapse of the fragile cosmopolitanism that once characterized parts of the Ottoman Empire, especially its port cities.
The map of the Middle East
The political map of the modern Middle East is considered to be the product of French and British scheming in the aftermath of World War I and the collapse of the Ottoman Empire. But Russia played its part as well, assenting to the 1916 Sykes-Picot agreement upon whose lines the boundaries of the region are partially (but not entirely) drawn.
The Bolshevik revolution voided some of the commitments made to Moscow -- which included control over Istanbul as well as a mandate for eastern Anatolia. But British and French strategists at the time were fully aware of the shadow of Russia, and arrayed their spheres of influence accordingly.
The Arab states that eventually emerged have all grappled with their own dysfunctions, challenges of governance, identity and ethnicity that still carry the seeds of far older conflicts.
