Medzev, commonly known as Metzenseifen, is a town and large municipality in Košice-okolie District in the Košice Region of eastern Slovakia. It is one of several towns in Bodva Valley. Other towns in Bodva Valley include: Jasov, Lucia Bania, Vyšný Medzev (Upper Metzenseifen), and Stos. Historically, It belonged to one of the original mountain towns in the Lower Zips/Dolný Spis: Gelnica/Göllnitz, Smolník/Schmöllnitz, Nálepkovo/Wagendrüssel, Krompachy/Krompach, Mníšek nad Hnilcom/Einsiedel, Švedlár/Schwedler.
Any official documents regarding the founding of Metzenseifen have yet to be found and were likely destroyed in the Counter-Reformation. Much of the historical records obtained regarding the history of Medzev come from the monastery in Jasov. As shown in the timeline, the departure of the Mongols in 1241 prompted King Béla IV to rebuild Hungary as quickly as possible. It is known that he invited Germans as part of his recolonization effort. Whether he directly invited the particular settlers of Metzenseifen remains unknown, but possible. The first official document from the Bodva Valley is that of a legal document from 1272, which describes the litigation of forestry rights between Vyšný Medzev/Upper Metzenseifen and Jasov. It could be extrapolated that Metzenseifen was founded sometime between 1241 and 1272.
