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 the Bosniaks
Since the 1990s, the name has been adopted outside of Bosnia itself, onto the Slavic Muslim population of other former Yugoslav republics such as Serbia and Macedonia. It allows a Bosniak/Bosnian distinction to match the Serb/Serbian and Croat/Croatian distinctions between ethnicity and residence.
