context_page_description: The history of Pomerania starts shortly before 1000 AD with ongoing conquests by newly arrived Polans rulers. Before that the area was recorded nearly 2000 years ago as Germania, and in modern-day times Pomerania is split between Germany and Poland. The name Pomerania comes from the Slavic po more, which means Land at the Sea.
  Settlement in the area started by the end of the Vistula Glacial Stage, about 13,000 years ago. Archeological traces have been found of various cultures during the Stone and Bronze Age, of Veneti and Germanic peoples during the Iron Age and, in the Middle Ages, Slavic tribes and Vikings. Starting in the 10th century, Piast Poland on several occasions acquired parts of the region from the south-east, while the Holy Roman Empire and Denmark reached the region in augmenting their territory to the west and north.
  In the High Middle Ages, the area became Christian and was ruled by local dukes of the House of Pomerania and the Samborides, at various times vassals of Denmark, the Holy Roman Empire and Poland.
