Henry

Henry (before 1066 – 22 March or 7 June 1127) was an Obotrite prince or king (1093–1127) from the Nakonid dynasty; he was regarded by contemporaries as "King of the Slavs" (rex Slavorum). 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.
