Some groups of nationalist Turks have claimed that the Circassians are of Turkic origin, but no scientific evidence has been published to support this claim, and has been strongly denied by Circassians, impartial research, linguists and historians around the world. Circassian language is not similar to the Turkish language except for borrowed words. According to various historians, the Circassian origin of the Sind-Meot tribes refutes the claim that the Circassians are of Turkic origin. The community, including Circassians, is today classified as "White Caucasian Peoples". Still, some Turkic groups have persisted in claiming Circassians are of Turkic origin, and argued that no proof is needed.
