OstsiedlungOstsiedlung (ˈɔstˌziːdlʊŋ, literally "East settlement") is the term for the Early Medieval and High Medieval migration of ethnic Germans into the territories in the eastern part of Francia, East Francia, and the Holy Roman Empire and beyond; and the consequences for settlement development and social structures in the areas of settlement. Generally sparsely and in some inland areas only relatively recently populated by Slavic, Baltic and Finnic peoples, the most settled area was known as Germania Slavica.
HolsteinHolstein (ˈhɔlʃtaɪn; Holsteen; Holsten; Holsatia) is the region between the rivers Elbe and Eider. It is the southern half of Schleswig-Holstein, the northernmost state of Germany. Holstein once existed as the German County of Holstein (Grafschaft Holstein; 811–1474), the later Duchy of Holstein (Herzogtum Holstein; 1474–1866), and was the northernmost territory of the Holy Roman Empire. The history of Holstein is closely intertwined with the history of the Danish Duchy of Schleswig (Slesvig).
LübeckLübeck (ˈlyːbɛk; Low German: Lübęk or Lübeek [ˈlyːbeːk]; Latin: Lubeca; Danish: Lybæk), officially the Hanseatic City of Lübeck (Hansestadt Lübeck), is a city in Northern Germany. With around 216,000 inhabitants, it is the second-largest city on the German Baltic coast as well as in the state of Schleswig-Holstein, after its capital of Kiel, and is the 36th-largest city in Germany. The city lies in the Holsatian part of Schleswig-Holstein, on the mouth of the Trave, which flows into the Bay of Lübeck in the borough of Travemünde, and on the Trave's tributary Wakenitz.
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.
High Middle AgesThe High Middle Ages, or high medieval period, was the period of European history that lasted from AD 1000 to 1350. The High Middle Ages were preceded by the Early Middle Ages and were followed by the Late Middle Ages, which ended around AD 1500 (by historiographical convention). Key historical trends of the High Middle Ages include the rapidly increasing population of Europe, which brought about great social and political change from the preceding era, and the Renaissance of the 12th century, including the first developments of rural exodus and urbanization.
