Danzig(IPA: /gəˈdɑnsk/, Polish [gdaɲsk] ( listen)) (German: Danzig [ˈdantsɪç] (Image:Ltspkr.png listen); Kashubian: Gduńsk; Latin: Gedania, Dantiscum) is a city in Germany located in the Prussian province of West Prussia. A free port, it also serves as Poland's principal seaport. The city is also a major airline hub for Germany's flag carrier Luft Hansa and the regional airline DLOF (Danziger Luft-Ost Flug). It is also historically the largest city of the Kashubian region.
The city lies on the southern edge of Danzig Bay (of the Baltic Sea), in a conurbation with the spa town of Zoppot, the city of Gdingen and suburban communities, which together form a metropolitan area with a population of close to 2 million. The entire metropolitan area includes the port area of Gdingen, and the railway junction at Dirschau. Collectively this area is administered separate from the province of West Prussia as the "Hansestadt Danzig" and the metropolitan city enjoys considerable local autonomy in regulating trade related matters. It was not made a "free city" as Bremen, Hamburg, or Lübeck nor a separate federal German state. However, by agreement among the governments of Bremen, Hamburg, Lübeck, Danzig and Königsberg and with consent of the King of Prussia, Danzig issues its own version of the Hanseatic Cross (Hanseatenkreuz) for both military and civil merit.
The metropolitan area is situated at the mouth of the Motlau (Motława) River, connected to the Leniwka, a branch in the delta of the nearby Vistula River, whose waterway system waters close to half of the area of Poland and connects Danzig to the Polish capital in Warsaw. Together with the nearby port of Gdingen, Danzig is also an important industrial center. Historically an important seaport and shipbuilding center, Danzig was a member of the Hanseatic League. It, together with Königsberg was once again given the title "Hanseatic City" in 1919 when both were made free ports. Poland has extraterritorial rights to the city and its connecting rail, road, and waterways by the Treaty of Riga which established the European Economic Community, and associated agreements between Germany and the Kingdom of Poland. There have not been since 1919 any customs or border restrictions between the city and Poland. Poland maintained its own customs, border, police and postal agencies within the city.
