Germany / Deutschland » States & Provinces » Brandenburg (Preußen)
Long owned by the Hohenzollern family that ruled Prussia, this province was surrounded by Sachsen and Hannover to its west, Mecklenburg and Pommern on the north, Schlesien to its south and the eastern border included Westpreußen and Posen. After World War II, the areas of Brandenburg that were east of the Oder and Neisse Rivers went to Poland, which accounted for about one-third of its geography. The remaining area is now the modern state called Brandenburg. It surrounds the modern city-state of Berlin. Learn more: FamilySearch Wiki - Brandenburg and GenWiki - Brandenburg
