Before World War I, there were around 30,000 speakers of Bohtan Neo-Aramaic on the Plain of Bohtan, around the town of Cizre in Turkey's Sirnak Province. Mostly Assyrian Christians, their language was a northern dialect of Chaldean Neo-Aramaic, but already somewhat more conservative than the standard Alqosh dialect. With the Assyrian Genocide that hit the Assyrians in eastern Turkey at the end of the war, many were forced from their homes. A decimated population travelled from Bohtan and eventually resettled in Garbadani in southeastern Georgia, 530 km from their original home. Many of the speakers of Bohtan Neo-Aramaic are over sixty year of age. The younger generations tend to use Georgian or Russian instead.
The latest study of the language was carried out by Samuel Ethan Fox in 1999, showing that Bohtan Neo-Aramaic has retained many conservative features of Chaldean and Assyrian Neo-Aramaic which are not present in the standard Alqosh and Urmia dialects, but has also developed new features that are not present in other dialects.
