Bosnia (region)
Bosnia (/Босна; ) is the northern region of Bosnia and Herzegovina, encompassing roughly 81% of the country; the other eponymous region, the southern part, is Herzegovina. "Bosnia" is an informal term for the whole country.
History of Bosnia and Herzegovina
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.
