Nokturnal Mortum originally started as a death metal band called Suppuration in 1991, then turned to black metal and changed name to Crystaline Darkness but "had to change the name back in 1993/94 to Nocturnal Mortum because there already existed a band with that name in western underground." Then the band "changed the letter so that we wouldn't find a band with the same name again like it was the case with Crystaline Darkness." Nokturnal Mortum gained their first Western recognition with the release of their album Goat Horns, their second full-length album, notable for having two keyboardists play on the album, often on the same song, and for mixing traditional Ukrainian music with black metal.
The band's first albums were released through The End Records and (as licence pressings) through Nuclear Blast, but the label and band separated after releasing the album Nechrist and a re-release of the Lunar Poetry demo due to a disagreement. According to Varggoth, "We had a contract with The End Records but it was broken. We have different points of view. They didn't like our policy, we didn't like the way they do business. They owe us some money. That was enough for a conflict."
In autumn of 2014 band frontman Knjaz Varggoth (real name Yevhen Gapon, Ukrainian: Євген Гапон) published the statement declaring that he and Nokturnal Mortum was out of politics in order to avoid rumors concerning his personal views and band ideology.
