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.
Nakh peoples
There is considerable tension among Chechens about religion. This largely asserts itself in the conflict between the pan-Islamist/Wahhabi/Salafi creed which vows to "cleanse Islam of impurity and syncretism" (i.e. de-Chechenize Islam in Chechnya to bring it more in line with global Islam), and those who view the indigenous form as superior, or otherwise as a national custom to be defended. Among the claimant governments for the land of Ichkeria, both the Western exiled Chechen Republic of Ichkeria and the Russian installed Kadyrov regime are largely hostile to Wahhabism/Salafism, while the reaction of the Caucasus Emirate is considerably more positive, though still at times rather uncomfortable towards it (see certain statements by Dokka Umarov, for example). The Kadyrov government, meanwhile, opposes Wahhabism in name, but still rules Chechnya with a rather harsh interpretation of Sharia law, including banning of bare-headed women in public, mandatory Qu'ran study in schools (with the interpretation favored by the government promoted), the death penalty for suspected homosexuality and so on. The exiled Chechen Republic of Ichkeria, meanwhile, has consistently stated both that the indigenous interpretation is a national trait (to be preserved) and that Ichkeria should be a secular national state, and while Islam may certainly be a part of the Chechen identity at times, it is certainly neither a requirement nor more important than any other aspect.
