LuticiThe 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 (Redari, Redarii), Circipanians (Circipani), Kessinians (Kessini, Kycini, Chizzini) and Tollensians (Tholenzi). At least in part, the Lutici were a continuation of the Veleti.
ObotritesThe Obotrites (Obotriti, Abodritorum, Abodritos...) or Obodrites, also spelled Abodrites (Abodriten), were a confederation of medieval West Slavic tribes within the territory of modern Mecklenburg and Holstein in northern Germany (see Polabian Slavs). 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).
MecklenburgMecklenburg (ˈmeːklənbʊʁk; Mękel(n)borg ˈmɛːkəl(n)bɔrx) is a historical region in northern Germany comprising the western and larger part of the federal-state Mecklenburg-Western Pomerania. The largest cities of the region are Rostock, Schwerin, Neubrandenburg, Wismar and Güstrow. The name Mecklenburg derives from a castle named Mikilenburg (Old Saxon for "big castle", hence its translation into Neo-Latin and Greek as Megalopolis), located between the cities of Schwerin and Wismar.
Wendish CrusadeThe Wendish Crusade (Wendenkreuzzug) was a military campaign in 1147, one of the Northern Crusades and a part of the Second Crusade, led primarily by the Kingdom of Germany within the Holy Roman Empire and directed against the Polabian Slavs (or "Wends"). The Wends were made up of the Slavic tribes of Abrotrites, Rani, Liutizians, Wagarians, and Pomeranians who lived east of the River Elbe in present-day northeast Germany and Poland. The lands inhabited by the Wends were rich in resources, which played a factor in the motivations of those who participated in the crusade.
Duchy of SaxonyThe Duchy of Saxony (Hartogdom Sassen, Herzogtum Sachsen) was originally the area settled by the Saxons in the late Early Middle Ages, when they were subdued by Charlemagne during the Saxon Wars from 772 and incorporated into the Carolingian Empire (Francia) by 804. Upon the 843 Treaty of Verdun, Saxony was one of the five German stem duchies of East Francia; Duke Henry the Fowler was elected German king in 919.
