Deportation of the Chechens and Ingush
The Chechens and the Ingush speak languages that are closely related and have a degree of passive intelligibility, both being Vainakh languages. The Chechen-Russian conflict is one of the longest and most protracted conflicts in modern history, spanning three centuries. Its origins date back to 1785, when the Chechens fought against Russian expansionism into the Caucasus. The Caucasus War was fought between 1817 and 1864. The Russian Empire succeeded in annexing the area and subjugating its people, but also killed or deported numerous non-Russian peoples and was responsible for the Circassian genocide. The Circassians, the Ubykh and the Abaza were subsequently resettled to the Ottoman Empire. However, other Caucasus people were affected as well. There were up to 1.5 million Chechens in the Caucasus in 1847, but as a result of this war and ensuing expulsions, their number dropped to 140,000 in 1861, and then further to 116,000 in 1867. In 1865, at least 39,000 Chechens were exiled to the Ottoman Empire by the Russian Empire.
Chechens
Genetic tests on Chechens, though sparse and not sufficiently thorough so far, have shown roots mostly in the Caucasus as well as slight connections to and influences from the Middle East as well as Europe. As is the case with many other Caucasian peoples, Chechens are broadly connected with Europe on the Y-DNA (the paternal side) from all European regions, but narrowly closer to Western Europe in terms of mitochondrial DNA (the maternal side).
