Vojvodina's demographic history reflects its rich history and its former location at the border of the Ottoman and Habsburg empires and at the confluence of various peoples, making it a hotbed of invasion, colonization, and assimilation processes. Currently there are more than 25 ethnic groups living in Vojvodina and six official languages. Demographic history The area of Vojvodina had been inhabited since the Paleolithic period. Indo-European peoples moved into this area during three migration waves, which are dated in 4200 BC, 3300 BC, and 2800 BC respectively. Before the Roman conquest in the 1st century BC, Indo-European peoples of Illyrian, Thracian and Celtic origin inhabited the region. During the Roman administration (which extended to Syrmia and Banat), the original inhabitants were heavily Romanized, and would later be known as Vlachs. The region of Bačka, which did not belong to the Roman Empire, was populated by Iranian Sarmatians (Iazyges). After the end of Roman rule, the Romanized inhabitants of the area escaped to the Balkan Mountains (where they mixed with South Slavs) as well as the Romanian Carpathians (where they later were known as Romanians). Vojvodina was invaded by the Turanic nomads such as the Huns and Avars, as well as by the Germanic Goths, Gepids and Lombards, but after their military defeat, they were quickly absorbed by the local (Slavic) population, without leaving much ethnic traces in the region's population. During the early medieval migrations, Slavs (Severans, Abodrites, Braničevci, Timočani and Serbs) settled today's Vojvodina in the 6th and 7th centuries. According to some sources, pockets of Romanized populations remained in the area. Until the Hungarian conquest in the 10th century, the region had a dominant Slavic population. The region was conquered by the Principality of Hungary in the 10th century, and Hungarians started to settle in the area. Hungarians mainly settled in the northern part of the region, where they lived mixed with Slavs. Until the late 12th and early 13th century, the region was mainly populated by Slavs, after which the ethnic relations changed in favor of Hungarians. The larger number of Hungarians settled in the region since the 13th century. The presence of Slavs in the area increased again in the 14th century with the arrival of many Serbs from the south. During the Hungarian administration, much of the native local Slavs were Magyarized. Initially, the Hungarian language was spoken only by the knights and nobility of
