The Slavic deities were worshipped by the peoples of Eastern Europe, from Russia to the Balkans, before their Christianization. They venerated them in wooden idols and open-air sanctuaries, tied to the forces of nature and the seasons. With few written records, their beliefs survive mainly in folklore and popular traditions.
On Kupala night, the summer solstice, young people leapt over bonfires and floated flower crowns on the rivers. Maslenitsa saw off winter with pancakes in honor of the sun, and in Kiev prince Vladimir raised — and later toppled — a great idol of Perun.

At a glance
Chernobog (documented in medieval Latin as Zcerneboch or Zcerneboth by chronicler Helmold of Bosau, and linguistically reconstructed as *Čьrnobogъ in Common Slavic) is the divinity or mythical personification of misfortune, adversity, and ill fortune among the West Slavic Polabian tribes (specifically the Wagri and Obodrites). His sole contemporary medieval documentary testimony dates from the mid-12th century, recorded by the Saxon priest and missionary Helmold in his celebrated Chronica Slavorum (c. 1168–1169, Book I, Chapter 52). In this passage, Helmold notes with amazement that the Slavs, during communal feasts and drinking bouts (in conviviis et compotationibus suis), passed around a sacrificial bowl over which they pronounced words of execration in the name of two gods: the 'good god' (bonus deus), to whom they attributed all fortunate events and prosperity, and the 'bad god' (malus deus), whom they designated in their own Slavic tongue as Diabol or Zcerneboch ('that is, the Black God', id est nigrum deum), holding him responsible for every hardship, defeat, and tragedy in mortal life. In the 16th century, Renaissance German and Pomeranian chroniclers — notably Thomas Kantzow in his Chronica Pomerania (1538) and Sebastian Münster in his Cosmographia (1550) — expanded upon Helmold's account, creating and popularizing in European scholarship the symmetrical literary opposition between Chernobog and Belobog ('The White God'). Modern critical historiography and Slavic comparative linguistics (led by scholars such as Aleksander Brückner, Stanisław Urbańczyk, Henryk Łowmiański, and Michał Łuczyński) have demonstrated that Chernobog did not constitute an authentic theological pagan deity within an organized polytheistic pantheon, but rather an archaic metaphorical idiom for 'ill fate' (čŕ̥nъ bogъ, identical in meaning to modern Slavic vernacular expressions like czarna dola or crna sudba), which Helmold interpreted through the lens of Christian dualism as an embodiment of the devil.
