Its territorial center was in the modern district of Herzogtum Lauenburg and originally its eponymous capital was Lauenburg upon Elbe, though in 1619 the capital moved to Ratzeburg.  - Bogislaw X of Pomerania, "the Great", (3 June 1454  5 October 1523) was Duke of Pomerania from 1474 until his death in 1523.  - Schleswig-Holstein is the northernmost of the 16 states of Germany, comprising most of the historical duchy of Holstein and the southern part of the former Duchy of Schleswig. Its capital city is Kiel; other notable cities are Lübeck and Flensburg.  - Pomerania-Stolp was one of the partitions of the Duchy of Pomerania. Centered in Supsk, it was created from another partition of the Duchy of Pomerania, Pomerania-Wolgast, to satisfy Bogislaw V, Duke of Pomerania in 1368, and existed until 1459, when it was inherited by Eric II of Pomerania-Wolgast. In 1474, it was merged to the partition of Bogislaw X, Duke of Pomerania, who four years later became the sole duke of Pomerania.  - Lower Saxony is a German state ("Bundesland") situated in northwestern Germany and is second in area, with , and fourth in population (8 million) among the sixteen "Länder" of Germany.

Its total length is .  - Ratzeburg is a town in Schleswig-Holstein, Germany. It is surrounded by four lakesthe resulting isthmuses between the lakes form the access lanes to the town.

It is bordered by (from the west and clockwise) the district of Stormarn, the city of Lübeck, the state of Mecklenburg-Vorpommern (districts of Nordwestmecklenburg and Ludwigslust-Parchim), the state of Lower Saxony (districts of Lüneburg and Harburg), and the city state of Hamburg. The district of Herzogtum Lauenburg is named after the former Duchy of Saxe-Lauenburg.  - The Duchy of Pomerania was partitioned several times to satisfy the claims of the male members of the ruling House of Pomerania dynasty. The partitions were named after the ducal residences: Pomerania-Barth, -Demmin, -Rügenwalde, -Stettin, -Stolp, and -Wolgast. None of the partitions had a hereditary character, the members of the House of Pomerania inherited the duchy in common. The duchy thus continued to exist as a whole despite its division. The only exception was made during a war with the Margraviate of Brandenburg, when in 1338 Barnim III of Pomerania-Stettin was granted his partition as a fief directly from the Holy Roman Emperor, while Pomerania-Wolgast remained under formal Brandenburgian overlordship. However, already in 1348, German king and later emperor Charles IV again granted the Duchy of Pomerania as a whole and the Principality of Rügen as a fief to the dukes of both Pomerania-Stettin and Pomerania-Wolgast, nullifying Brandenburg's claims by granting Imperial immediacy.
