The probable origin of the village Betliar can be dated to the years 1280 and 1300. The first, so far known, written mention of the village is from 1330.
According to legend, the village was a mining settlement, originally in the part of today's Jánská dolina, where there were also mines, but during the earthquake it allegedly collapsed. A new settlement was established on both sides, then Krivý, today Betliarský brook.
The cadastre of the village (area 2,466 ha) is surrounded in the northeast by the Volovské vrchy zone, in the southwest by the Turecká mountain massif.
In the 14th - 15th and partly in the 16th century, the village also preserved its mining character. After the decline of mining, the population shifted to agriculture, logging and a diverse range of crafts.
In 1775 the village had 964 inhabitants, at a time of economic prosperity up to 1,400 inhabitants, today it has 940. In addition to sewerage and wastewater treatment (under construction), the village has an almost complete engineering network.
