History of Bosnia and Herzegovina - Middle Ages

Middle Ages

By the 6th century, Emperor Justinian had re-conquered the area for the Byzantine Empire. The Slavs, a migratory people from southeastern Europe, were allied by the Eurasian Avars in the 6th century, and together they invaded the Eastern Roman Empire in the 6th and 7th centuries, settling in what is now Bosnia and Herzegovina and the surrounding lands. More South Slavs came in a second wave, and according to some scholars were invited by Emperor Heraclius to drive the Avars from Dalmatia.

Modern knowledge of Bosnia in the western Balkans during the Dark Ages is patchy. Upon the looter invasions by the Avars and Slavs from 6th-9th century, bringing Slavic languages, both probably gave way to feudalism only with the might by the Frankish penetrating into the region in the late 9th century (Bosnia probably originated as one such pre-feudal entity). It was also around this time that the Bosnians were Christianized. Bosnia, due to its geographic position and terrain, was probably one of the last areas to go through this process, which presumably originated from the urban centers along the Dalmatian coast.
