The Dacians (/ˈdʃənz/; Latin: Daci [ˈd̪aːkiː]; Greek: Δάκοι,[2] Δάοι,[2] Δάκαι[3]) were a sub-group of the Thracian[4][5][6] people and they were the ancient inhabitants of the cultural region of Dacia, located in the area near the Carpathian Mountains and west of the Black Sea. This area includes mainly the present-day countries of Romania and Moldova, as well as parts of Ukraine,[7] Eastern Serbia, Northern Bulgaria, Slovakia,[8] Hungary and Southern Poland.[7] The Dacians spoke the Dacian language, a sub-group of Thracian, but were somewhat culturally influenced by the neighbouring Scythians and by the Celtic invaders of the 4th century BC.[citation needed]
