With a population of 466,631, Gdańsk is the capital and largest city of the Pomeranian Voivodeship and one of the most prominent cities within the cultural and geographical region of Kashubia.
It is Poland's principal seaport and the centre of the country's fourth-largest metropolitan area. The city is located on the southern edge of Gdańsk Bay (of the Baltic Sea), in a conurbation with the city of Gdynia, spa town of Sopot, and suburban communities, which together form a metropolitan area called the Tricity (Trójmiasto), with a population approaching 1. 4 million. Gdańsk is the capital of Gdańsk Pomerania and the largest city of north Poland. The city's history is complex, with periods of Polish rule, periods of Prussian or German rule, and periods of autonomy or self-rule as a "free city". In the early-modern age Gdańsk was a royal city of Poland. It was considered the wealthiest and the largest city of Poland, prior to the 18th century rapid growth of Warsaw. Between the world wars, the Free City of Danzig, having a German majority, was in a customs union with Poland and was situated between East Prussia and the so-called Polish Corridor.
