Nyitra County
A predecessor to Nyitra county may have existed as early as in the 9th century at the time of Great Moravia. Around 1000, Nyitra county arose as one of the first comitatus of the Kingdom of Hungary. The southern part, including the town Nyitra, was ruled as Uyvar Province between 1663–1685 by Ottoman Empire. The county shortly ceased to exist as a separate administrative unit between 1850 and 1860, when it was split into Upper Nyitra County (including Bán district from Trencsén County) and Lower Nyitra County (including Oszlány district from Bars County).
