The
Dacians (; , ) were an
Indo-European people, part of or related to the
Thracians. Dacians were the ancient inhabitants of
Dacia, located in the area in and around the
Carpathian Mountains and west of the
Black Sea. This area includes the present-day countries of
Romania and
Moldova, as well as parts of
Ukraine,
Eastern Serbia,
Northern Bulgaria,
Slovakia,
Hungary and Southern
Poland. The Dacians spoke the
Dacian language, believed to have been closely related to
Thracian, but were somewhat culturally influenced by the neighbouring
Scythians and by the
Celtic invaders of the 4th century BC.
