Chernobog and Belobog
Chernobog (lit. "Black God") and Belobog (lit. "White God") are a pair of Polabian deities. Chernobog appears in Helmold's Chronicle as a god of misfortune worshipped by the Wagri and Obodrites, while Belobog is not mentioned – he was reconstructed in opposition to Chernobog. Both gods also appear in later sources, but they are not considered reliable. Researchers do not agree on the status of Chernobog and Belobog: many scholars recognize the authenticity of these theonyms and explain them, for example, as gods of good and evil; on the other hand, many scholars believe that they are pseudo-deities, and Chernobog may have originally meant "bad fate", and later associated with the Christian devil.

Sources
In Latin records, this theonym is noted as Zcerneboch and zcerneboth.The 12th-century German monk and chronicler Helmold, who accompanied the Christianization missions to the Elbe Slavs, describes in his Chronicle of the Slavs the cult of Chernobog:

Belobog does not appear in any reliable sources – he was recreated in opposition to Chernobog.

Later sources
The next sources that speak of Chernobog and/or Belobog appear only in the 16th century. Around 1530, a Dominican friar from Pirna, Johan Lindner, recalls the gods in his compilation. Although he lived in or near the Lusatian region, he probably only used written sources and monastic stories, and not field research, which made many historians deem his work unreliable, including Georg Fabricius and Petrus Albinus. They believed that although his sources were numerous and varied, he used them uncritically. At the end of the 17th century, Abraham Frencel also mentioned the Chernobog in his list of the Lusatian gods. This information is also considered unreliable because it came into being late, when the Lusatian paganism was probably completely extinct and about half of the gods he mentioned are of Prussian origin.In 1538, the Pomeranian chronicler Thomas Kantzow in his Chronicle of Pomerania wrote:

Then Sebastian Münster, in Cosmographiae universalis of 1550, describes the harvest ritual associated with Svetovit and continues: "In general they (the Rugians) worshipped two gods, namely Belbuck and Zernebuck, as if a white and a black god, a good and an evil genius, God and Satan, as the source of good and evil, according to the error of the Manichaeans". The works of Kantzov and Münster are probably independent of each other (various forms of recording the name of the Belobog, the Chronicle of Pomerania was first published, but it was not published until the 19th century), but they use a common source, which, according to Miroslava Znayenko, could be the archive of the Abbey of Białoboki, where the Belobog was forged. Daniel Cramer, a theologian and professor from Szczecin, probably held in his hands a copy of a chronicle from this archive or saw a quote from it, because in his Pommerisches Kirchen-Chronicon he probably paraphrased a part of it:

Chernobog also appears in the anonymous Historia Caminensis as the god of the Vandals, which is based on a work by Münster (both works speak of the "error of the Manichaeans"). Chernobog and Belobog also appear in other minor texts.

Interpretations
There is no consensus in the academic community about the status of Chernobog and Belobog in Slavic mythology, or whether the two gods existed at all in Slavic mythology. Some researchers completely reject the existence of Belobog due to his non-appearance in the sources. At least four views have developed in scholarship:
Chernobog is an epithet of Satan, and Belobog arose secondarily in later literature
Chernobog and Belobog are Slavic deities (actual theonyms or epithets of other deities)
Chernobog and Belobog are names of Christian figures with pre-Christian origin
Chernobog and Belobog are pseudo-deities, they did not exist in either the Christian or pagan vocabulary

As deities
Helmold's information led to the 19th century concept according to which there was supposed to be dualism in Slavic religion, which reached the Slavs from the Iranian peoples (Scythians, Sarmatians or Bogomils); Chernobog and the hypothetical Belobog were compared to Ahriman and Ormuzd eternal enemies. In this spirit, Chernobog was interpreted by Alexander Hilferding. Later, Alexander Afanasyev and Alexander Famitsin considered the eastern counterpart of Belobog to be Belun (field spirit). None of these scholars, however, considered dualism an important element of Slavic religion; such a view was expressed only by Nikolay Kvashnin-Samarin in his amateur work Очерке славянской мифологии (1872), but his work is not considered important. Franciszek Slawski, in his Słownik prasłowiański, reconstructed the Proto-Slavic *bělъ bogъ "white, bright deity" and Proto-Slavic dial. *čŕ̥nъ bogъ "black deity, dark deity", for the latter the main attestation is supposed to be Helmold's account. Such dualism was advocated, for example, by Aleksander Gieysztor, Vyacheslav Ivanov and Vladimir Toporov considered Chernobog to be a god who brings misfortune. Some authors have tried to prove the cult of Chernobog with the names of the Czorneboh and Bieleboh mountains in Upper Lusatia, where the gods are said to have been worshipped, but these names were not created until the modern era due to the popularity of the gods in the culture of those areas. When considering the authenticity of the gods, place names that are said to refer to Chernobog and Belobog are also mentioned as arguments, such as the village of Chernobozhye in Russia or the village of Chernobozhna in Ukraine, also the neighboring villages of Černíkovice and Bělbožice in the Czech Republic are said to be evidence of the authenticity of the cult of Chernobog and Belobog, although the former most likely comes from a personal name.

As pseudo-deities
On the other hand, many researchers considered Chernobog merely a personification of bad luck, some mistake by Helmold or a pseudo deity in general. Andrzej Szyjewski considered Chernobog only a pejorative epithet for the devil, Stanisław Urbańczyk said:

His view was supported by Jerzy Strzelczyk. Chernobog was also supposed to be the personification of bad luck according to Martin Pitro and Petr Vokáč and Stanisław Rosik.Aleksander Brückner negated the existence of Chernobog (and Belobog) in Slavic religion and claimed that Chernobog was created under the influence of Christianity, including medieval depictions of the devil as a black demon, and compared him to the alleged Prussian god Pikulas, which ultimately derives from the Polish word piekło "hell". The view was supported by e.g. Henryk Łowmiański.An extended analysis of Chernobog and Belobog was made by Michał Łuczynski. He points out, first of all, that Slavic linguistic material makes it easy to conclude that words like black god and white god have a pan-Slavic range and a Proto-Slavic origin. The attestations of the black god are as follows: Slovincian čǻrnï bȯ́u̯g "devil", Silesian Czorny Bóg "evil spirit, devil", and toponyms: Russian Chernobozhye, Ukrainian Chernobozhna and Serbian Černobožeskij gorodok; the attestations of the white god: Slovincian bjǻu̯lï bȯ́u̯g "God", Silesian Bioły Bóg "a good, human-friendly deity; a good spirit", Serbian dial. bel(i) bog "fate", Bulgarian dial. byal bog "luck, success", and toponyms: Czech Bělbog, Bělbožice, Russian Belye bogi, Belovozhskiy monastyr, German Belboh, Belbog, Belbuk and others. According to him, the above material leads him to assume that: the words black and white used in the expressions were used in their metaphorical sense, successively "bad" and "good", and the word god was used in its abstract sense of "fate, luck, fate". Accordingly, Proto-Slavic *čŕ̥nъ bogъ meant "bad fate", and *bělъ bogъ "good fate" and this was their original meaning. Evidence of this etymology is provided by analogies, e.g. Polish czarna dola, Serbian crna sreća, crna sudbina, Croatian crna sudba all meaning "bad fate", lit. "black fate". Subsequently, these terms passed into personal names category and were used to describe God/Jesus and the devil as figures responsible for good fate and bad fate. Consequently, he considers Helmold's Chernobog to be a pseudo-deity, which has been misidentified by modern scholars as a deity due to Helmold's calque of black god and white god into Latin as niger deus and bonus deus which suggests that Slavic bog used in these terms = Latin deus, and personal names *Čŕ̥nobogъ "devil" and *Bělobogъ "God/Jesus" as semantic neologisms belonging to the Christian cultural circle, not pagan, as religious, not mythological terms, as may be further indicated by the toponymy (the Christian places of worship in Bielboh and Belovozhskiy monastyr).

In popular culture
In Disney productions
An alternative version of Chernobog named Chernabog appears in the symphonic poem Night on Bald Mountain by Russian composer Modest Mussorgsky. He is depicted as a giant winged demon summoning the souls of the dead. One segment of Walt Disney's Fantasia (1940) was based on this work. The character may have been originally intended as a representation of Satan; in the film, Disney calls him "Satan himself". A full-length live-action film based on the segment was announced in 2015.
