They settled in Banat during great migrations of Balkanic peoples caused by Ottoman conquest (1552–1716), and also during Austrian administration (1716–1776). According to theories of origin of Romanians, they emanated from Romanization of the Roman Province of Dacia, i.e. they descending from the antique populations of Dacians (Getae, Thracians) and Roman legionnaires and colonists. It is assumed that this Romance population survived great migrations of early Middle Ages somewhere in Transylvanian mountains, from where it later spread to Wallachia, Moldova, Banat and other areas. Romanian is one of six official languages of Vojvodina, spoken by 1.08% of inhabitants.
