Located in Kashubia in Eastern Pomerania, Gdynia is part of a conurbation with the spa town of Sopot, the city of Gdańsk and suburban communities, which together form a metropolitan area called the Tricity (Trójmiasto), with a population of over a million people.
The area of the later city of Gdynia shared its history with Pomerelia (Eastern Pomerania); in prehistoric times it was the center of Oksywie culture; it was later populated by Slavs with some Baltic Prussian influences.
Construction of the seaport
The decision to build a major seaport at the Gdynia village was made by the Polish government in the winter of 1920, in the midst of the Polish-Soviet War (1919–1920). The authorities and seaport workers of the Free City of Gdańsk felt Poland's economic rights in the city were being misappropriated to help fight the war. German dock workers went on strike, refusing to unload shipments of military supplies send from the West to aid the Polish army, and Poland realized the need for a port city it was in complete control of, economically and politically.
Construction of Gdynia seaport was started in 1921, but because of financial difficulties was conducted slowly and with interruptions. It was accelerated after the Sejm (Polish parliament) passed the Gdynia Seaport Construction Act on 23 September 1922. By 1923 a 550-metre pier, 175 metres of a wooden tide breaker, and a small harbour had been constructed. Ceremonial inauguration of Gdynia as a temporary military port and fishers' shelter took place on 23 April 1923, and the first major seagoing ship arrived on 13 August 1923.
To speed up the construction works, the Polish government in November 1924 signed a contract with the French-Polish Consortium for Gdynia Seaport Construction, which by the end of 1925 had built a small seven-metre-deep harbour, the south pier, part of the north pier, a railway, and had also ordered the trans-shipment equipment. The works were going more slowly than expected, however. They accelerated only after May 1926, because of an increase in Polish exports by sea, economic prosperity, the outbreak of the German–Polish trade war which reverted most Polish international trade to sea routes, and also thanks to the personal engagement of Eugeniusz Kwiatkowski, Polish Minister of Industry and Trade, also responsible for construction of Centralny Okręg Przemysłowy. Till the end of 1930 docks, piers, breakwaters and many auxiliary and industrial installations were constructed (such as depots, trans-shipment equipment, and a rice processing factory) or started (such as a large cold store).
Trans-shipments rose from 10,000 tons (1924) to 2,923,000 tons (1929). At this time Gdynia was the only transit and special seaport designed for coal exports. In the years 1931–1939 the Gdynia harbour was further extended to become a universal seaport. In 1938 Gdynia was the largest and most modern seaport on the Baltic Sea, as well as the tenth biggest in Europe. The trans-shipments rose to 8.7 million tons, which was 46% of Polish foreign trade. In 1938 the Gdynia shipyard started to build its first full-sea ship, the Olza.
Construction of the city
The city was constructed later than the seaport. In 1925 a special committee was inaugurated to build the city; city expansion plans were designed and city rights were granted in 1926, and tax privileges were granted for investors in 1927. The city started to grow significantly after 1928.
A new railway station and the Post Office were completed. The State railways extended their lines, built bridges and also constructed a group of houses for their employees. Within a few years houses were built along some of road leading northward from the Free City of Gdańsk to Gdynia and beyond. Public institutions and private employers helped their staffs to build houses.
During World War II (1939–1945)
The city and seaport were occupied in September 1939 by German troops and renamed Gotenhafen after the Goths, an ancient Germanic tribe, who had lived in the area. Some 50,000 Polish citizens, who after 1920 had been brought into the area by the Polish government after the decision to enlarge the harbour was made, were expelled to the General Government. Kashubians who were suspected to support the Polish cause, particularly those with higher education, were arrested and executed. The main place of execution was Piaśnica (Groß Plaßnitz), where about 12,000 were executed. The German gauleiter Albert Forster considered Kashubians of "low value" and did not support any attempts to create a Kashubian nationality. Some Kashubians organized anti-Nazi resistance groups, "Gryf Kaszubski" (later "Gryf Pomorski"), and the exiled "Zwiazek Pomorski" in Great Britain.
The harbour was transformed into a German naval base. The shipyard was expanded in 1940 and became a branch of the Kiel shipyard (Deutsche Werke Kiel A.G.). Gotenhafen became an important base, due to its being relatively distant from the war theater, and many German large ships—battleships and heavy cruisers—were anchored there. During 1942, Dr Joseph Goebbels authorized relocation of SS Cap Arcona to Gotenhafen Harbour as a stand-in for RMS Titanic during filming of the German-produced movie Titanic, directed by Herbert Selpin.
The seaport and the shipyard both witnessed several air raids by the Allies from 1943 onwards, but suffered little damage. Gotenhafen was used during winter 1944–45 to evacuate German troops and refugees trapped by the Red Army. Some of the ships were hit by torpedoes from Soviet submarines in the Baltic Sea on the route West. For example, the ship Wilhelm Gustloff sank taking about 9,400 people with her – the worst loss of life in a single sinking in maritime history. The seaport area was largely destroyed by withdrawing German troops and millions of encircled refugees in 1945 being bombarded by Soviet Military (90% of the buildings and equipment were destroyed) and the harbour entrance was blocked by the German battleship Gneisenau that had been brought to Gotenhafen for major repairs.
After World War II
In the Polish 1970 protests, worker demonstrations took place at Gdynia Shipyard. Workers were fired upon by the police. The fallen (e.g. Brunon Drywa) became symbolized by a fictitious worker Janek Wiśniewski, commemorated in a song by Mieczysław Cholewa, Pieśń o Janku z Gdyni. One of Gdynia's important streets is named after Janek Wiśniewski. The same person was portrayed by Andrzej Wajda in his movie Man of Iron as Mateusz Birkut.
On December 4, 1999, a storm destroyed a huge crane in a shipyard, which was able to lift 900 tons.
