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.
Chechen language
Dialects of Chechen can be classified by their geographic position within the Chechen Republic. The dialects of the northern lowlands are often referred to as "Oharoy muott" (literally "lowlander's language") and the dialect of the southern mountain tribes is known as "Laamaroy muott" (lit. "mountainer's language"). Oharoy muott forms the basis for much of the standard and literary Chechen language, which can largely be traced to the regional dialects of Urus-Martan and contemporary Grozny. Laamaroy dialects include (but are not limited to) Chebarloish, Sharoish, Itum-Qalish, Kisti, and Himoish. Until recently, however, Himoy was undocumented and was considered a branch of Sharoish, as many dialects are also used as the basis of intertribal (teip) communication within a larger Chechen "tukkhum". Laamaroy dialects such as Sharoish, Himoish and Chebarloish are more conservative and retain many features from Proto–Chechen. For instance, many of these dialects lack a number of vowels found in the standard language which were a result of long-distance assimilation between vowel sounds. Additionally, the Himoy dialect preserves word-final, post-tonic vowels as a schwa [ə], indicating Laamaroy and Ohwaroy dialects were already separate at the time that Oharoy dialects were undergoing assimilation.
