Ayrums ( Azerbaijani: Ayrımlar) are a sub-ethnic group of Azerbaijanis in the Caucasus. During the late nineteenth and early twentieth centuries, some migrated to Iran and to Turkey. At least six towns in northwestern Azerbaijan and northeastern Armenia have been named after the tribe: Ayrum, Mets Ayrum, Bağanis Ayrum, Quşçu Ayrım, Yuxarı Ayrım, Mollaayrım. This is because the traditional territory of the tribe lay in the area between the modern-day states of Georgia, Armenia, and Azerbaijan. There is no relation between Ayrom's and the Greek Orthodox, Turkic-speaking Urum people. The confusion is rooted from the lack of the Turkic sound "-ı" in Persian and its consequent representation by "-u".
