Gdańsk is a Polish city on the Baltic coast. It is the capital of the Pomeranian Voivodeship, Poland's principal seaport and the centre of the country's fourth-largest metropolitan area.
The city lies on the southern edge of Gdańsk Bay, in a conurbation with the city of Gdynia, spa town of Sopot, and suburban communities, which together form a metropolitan area called the Tricity, with a population approaching 1.4 million. Gdańsk itself has a population of 460,427, making it the largest city in the Pomerania region of Northern Poland.
Gdańsk is the capital of Gdańsk Pomerania and the largest city of Kashubia. With its origins as a Polish stronghold erected in the 980s by Mieszko I of 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 was in a customs union with Poland and was located between German East Prussia and the so-called Polish Corridor.
