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.
Caucasus Emirate
Following the dissolution of the Soviet Union, Chechen nationalists, led by Dzhokhar Dudayev, declared the secession of Chechnya from Russia as an independent Chechen Republic of Ichkeria (ChRI). Following two devastating wars with the Russian Federation in the nineties, the ChRI fought an insurgency against the Russian forces and their Chechen allies from 2000, initially under the leadership of Aslan Maskhadov. Although the ChRI was largely founded by Sufi Muslims motivated by nationalism, over time the literalist Salafist form of Islam became increasingly popular with some Chechens, leading to a schism between nationalists and Salafists. As many of the original nationalist figures were killed by Russian forces, the insurgency took on an increasingly Salafist tone embodied by commanders like Shamil Basayev and the Arab fighter Khattab. Many of the surviving nationalists gave up the fight, and by the time Dokka Umarov was declared President of Ichkeria in June 2006, Islamists held increasing influence in the movement.
