In the Middle Ages, the Kremnica Mountains (German: Kremnitzer Berge) were an important gold mining area within Upper Hungary (German: Oberungarn) and directly subordinate to the Hungarian monarch. Numerous villages, mostly spread out in the mountainous and hilly areas, were agricultural and developed a special kind of German subculture.
In 1328, King Charles I granted Kremnica town privileges, followed by the foundation of Kunešov (German: Kuneschhau) in 1342, Sklené (German: Glaserhau) in 1360, Kremnické Bane (German: Johannesberg) in 1361, Turček/Dolný Turček (German: Unter-Turz) in 1371, Horná Štubňa (German: Oberstuben) in 1390, Krahule (German: Blaufuß) in 1422, and Janova Lehota (German: Drexlerhau) in 1487.
The largest Hauerland municipality was Handlová (German: Krickerhau), established in 1367 within the Bojnice (German: Weinitz) castle estates, where in the 19th century, coal deposits were discovered. In the northern part, the town of Nitrianske Pravno was founded about 1337, followed by Malinová (German: Zeche) in 1339, Kľačno (German: Gaidel), Tužina (German: Schmiedshau) about 1350, Vrícko (German: Münnichwies) in 1488, and Chvojnica (German: Fundstollen) in 1614.
Over the centuries, the German-speaking population of these areas gradually diminished, decimated already in the Hussite Wars of the 1420s and 1430s respectively, in the 16th century Ottoman–Habsburg wars, and again by insurgent Hungarian troops under Stephen Bocskay in 1605/06, succeeded by the forces of Gabriel Bethlen and George I Rákóczi.
