List of rulers of Mecklenburg

As allies of the Carolingian kings and the empire of their Ottonian successors, the Obotrites fought from 808 to 1200 against the kings of Denmark, who wished to rule the Baltic region independently of the empire. When opportunities arose, for instance upon the death of an emperor, they would seek to seize power; and in 983 Hamburg was destroyed by the Obotrites under their king, Mstivoj. At times they levied tribute from the Danes and Saxons. Under the leadership of Niklot, they resisted a Christian assault during the Wendish Crusade.

The Limes Saxoniae forming the border between the Saxons to the west and the Obotrites to the east

German missionaries such as Vicelinus converted the Obotrites to Christianity. In 1170 they acknowledged the suzerainty of the Holy Roman Empire, leading to Germanisation and assimilation over the following centuries. The ruling clan of the Obotrites kept its power throughout the Germanisation and ruled their country (except of a short interruption in Thirty Years' War) as House of Mecklenburg until the end of monarchies in Germany in November Revolution 1918.

The rulers of Obotrite lands were later the Dukes and Grand Dukes of Mecklenburg.

From the 7th through the 12th centuries, the area of Mecklenburg was taken over by Western Slavic peoples, most notably the Obotrites and other tribes that Frankish sources referred to as "Wends". The 11th century founder of the Mecklenburgian dynasty of Dukes and later Grand Dukes, which lasted until 1918, was Nyklot of the Obotrites.

In the late 12th century, Henry the Lion, Duke of the Saxons, conquered the region, subjugated its local lords, and Christianized its people, in a precursor to the Northern Crusades. From 12th to 14th century, large numbers of Germans and Flemings settled the area (Ostsiedlung), importing German law and improved agricultural techniques. The Wends who survived all warfare and devastation of the centuries before, including invasions of and expeditions into Saxony, Denmark and Liutizic areas as well as internal conflicts, were assimilated in the centuries thereafter. However, elements of certain names and words used in Mecklenburg speak to the lingering Slavic influence. An example would be the city of Schwerin, which was originally called Zuarin in Slavic. Another example is the town of Bresegard, the 'gard' portion of the town name deriving from the Slavic word 'grad', meaning city or town.

Table of rulers

(Note: The current numbering system established for the rulers of Mecklenburg is based in the following: the Mecklenburgian group (Mecklenbugr, and then Schwerin, later Gustrow and Strelitz) form one group of a single numbering. The other parts of Mecklenburg (Parchim, Werle and divisions, Rostock and Stargard) have their own and independent numberings for their rulers.)
