The Obotrites or Obodrites, also spelled Abodrites, were a confederation of medieval West Slavic tribes within the territory of modern Mecklenburg and Holstein in northern Germany. For decades, they were allies of Charlemagne in his wars against the Germanic Saxons and the Slavic Veleti. The Obotrites under Prince Thrasco defeated the Saxons in the Battle of Bornhöved (798). The still-Pagan Saxons were dispersed by the emperor, and the part of their former land in Holstein north of Elbe was awarded to the Obotrites in 804, as a reward for their victory. This however was soon reverted through an invasion of the Danes. The Obotrite regnal style was abolished in 1167, when Pribislav was restored to power by Duke Henry the Lion, as Prince of Mecklenburg, thereby founding the Germanized House of Mecklenburg.
Helmold of Bosau was a Saxon historian of the 12th century and a priest at Bosau near Plön. He was a friend of the two bishops of Oldenburg in Holstein, Vicelinus and Gerold, who did much to Christianize the Polabian Slavs.
Chernobog and Belobog are an alleged 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.
Svetovit, also known as Sventovit and Svantovit amongst other variants, is the god of abundance and war, and the chief god of the Slavic tribe of the Rani, and later of all the Polabian Slavs. His organized cult was located on the island of Rügen, at Cape Arkona, where his main temple was also located. According to the descriptions of medieval chroniclers, the statue representing this god had four heads, a horn and a sword, and to the deity himself were dedicated a white horse, a saddle, a bit, a flag, and eagles. Once a year, after the harvest, a large festival was held in his honor. With the help of a horn and a horse belonging to the god, the priests carried out divinations, and at night the god himself rode a horse to fight his enemies. His name can be translated as "Strong Lord" or "Holy Lord". In the past it was often mistakenly believed that the cult of Svetovit originated from St. Vitus. Among scholars of Slavic mythology, Svetovit is often regarded as a Polabian hypostasis of Pan-Slavic god Perun. His cult was destroyed in 1168.
Gottschalk, sometimes rendered as Godescalc, was a prince of the Obotrite confederacy from 1043 to 1066. He established a Polabian Slavic kingdom on the Elbe in the mid-11th century. His object in life seems to have been to collect the scattered tribes of the Slavs into one kingdom, and to make that kingdom Christian.
Drahomíra of Stodor was Duchess consort of Bohemia from 915 to 921, wife of the Přemyslid duke Vratislaus I. She also acted as regent of the Duchy of Bohemia from 921 to 924 during the minority of her son Wenceslaus. She is chiefly known for the murder of her mother-in-law Ludmila of Bohemia by hired assassins.
Radegast or Radogost is, according to medieval chroniclers, the god of the Polabian Slavs, whose temple was located in Rethra. In modern academic literature, however, the dominant view is that Radegast is a local nickname or a local alternative name of the solar god Svarozhits, who, according to earlier sources, was the chief god of Rethra. Some researchers also believe that the name of the town, where Svarozhits was the main deity, was mistakenly taken for a theonym. A popular local legend in the Czech Republic is related to Radegast.
Gesta Hammaburgensis ecclesiae pontificum is a historical treatise written between 1073 and 1076 by Adam of Bremen, who made additions (scholia) to the text until his death . It is one of the most important sources of the medieval history of Northern Europe, and the oldest textual source reporting the discovery of coastal North America.
The Wagri, Wagiri, or Wagrians were a tribe of Polabian Slavs inhabiting Wagria, or eastern Holstein in northern Germany, from the ninth to twelfth centuries. They were a constituent tribe of the Obodrite confederacy.
Kruto the Wend, son of Grin or Grinus, was a prince of Wagria. James Westfall Thompson believed his family belonged to the Rani of Rugia.
Henry was an Obotrite prince or king (1093–1127) from the Nakonid dynasty; he was regarded by contemporaries as "King of the Slavs". The Obotrite realm reached its greatest area during Henry's rule, extending from the Elbe to the Oder and from the Havelland to the Baltic Sea.
Budivoj, Buthue, or Butue was the eldest son of Gottschalk, an Obotrite prince, by a mistress. He allied with the dukes of Saxony in order to recover the power and position of his father, lost since Gottschalk's death (1066) to the pagan Kruto.
The Rani or Rujani were a West Slavic tribe based on the island of Rugia (Rügen) and the southwestern mainland across the Strelasund in what is today northeastern Germany.
Niklot or Nyklot was a chief or prince of the Slavic Obotrites and an ancestor of the House of Mecklenburg. He became chief of the Obotrite confederacy, including the Kissini and the Circipani, between the years 1130 and 1131. He remained in this position until his death in 1160. At the same time he was Lord of Schwerin, Quetzin and Malchow. For nearly 30 years he resisted Saxon princes, especially Henry the Lion during the Wendish Crusade.
The Nakonids were the leading noble family of the Slavic peoples of the Elbe River from ca. 960 until 1129. They were themselves of Obotrite origin and engineered the formation of a Slavic principality in the region. They became extinct in the male line in the early 12th century. Their capital was Mecklenburg Castle.
Pribislav was an Obotrite prince and the first Prince of Mecklenburg (1167–1178).
The Lutici or Liutizi(known by various spelling variants) were a federation of West Slavic Polabian tribes, who between the 10th and 12th centuries lived in what is now northeastern Germany. Four tribes made up the core of the federation: the Redarians, Circipanians (Circipani), Kessinians and Tollensians (Tholenzi). At least in part, the Lutici were a continuation of the Veleti. In contrast to the former and the neighboring peoples, the Lutici were not led by a Christian monarch or duke, rather power was asserted through consensus formed in central assemblies of the social elites, and the Lutici worshipped nature and several deities. The political and religious center was Radgosc.
Rethra was, in the 10th to the 12th centuries, the main town and political center of the Slavic Redarians, one of the four major Lutician tribes, located most likely in present-day Mecklenburg. It was also a major worship center, devoted to the cult of the Slavic deity Radegast-Swarożyc.
Hennil or Bendil is an alleged agrarian Slavic god worshipped by the Polabian Slavs. He was mentioned by Bishop Thietmar in his Chronicle as a god who was represented by a staff crowned by a hand holding a ring, which is interpreted as a symbol of fertility. However, there is no general consensus on the authenticity of the deity.
