I, there were 3,000 Polish inhabitants in the city, including some wealthy industrialists and merchants. Among them was Kazimierz Pruszak, director of the Goleniów (then Gollnow) industrial works, who predicted eventual "return of Szczecin to Poland". The population grew to 236,000 in 1910 and 382,000 in 1939. During the Franco-Prussian War (1870–1871), the Prussians established a prisoner-of-war camp for around 1,700 French troops in the city, of which 600 died. There is a memorial at the site of the former cemetery of the French POWs. Weimar Republic and Nazi Germany (1918-1945) In 1918, the city became part of the new Free State of Prussia, part of the Weimar Republic. After World War I, the economy of Stettin declined again because the seaport was separated from its agricultural supply areas in Posen with the creation of the Second Polish Republic. In the deeply flawed March 1933 German federal election the Nazi Party received 79,729 votes in the city, i.e. nearly half of the votes cast. The socialists, communists and conservative nationalists have also received noticeable support, receiving 22%, 13% and 11.4% of the votes respectively.

The city was a major centre of weapons industry (including the car production Stoewer). The Polish resistance movement was active in the city and conducted espionage of the Kriegsmarine, infiltrated the local German industry, distributed underground Polish press, and facilitated escapes of Polish and British prisoners of war who fled from German POW camps via the city's port to neutral Sweden. 65% of the city's buildings and almost all of the city centre, seaport, and industry were destroyed during the Allied air raids in 1944, and heavy fighting between the German and Soviet armies (26 April 1945). Polish diaspora In the interwar period Polish presence fell to 2,000 people. Between 1925 and 1939 a Polish Consulate existed, which initiated the foundation of a Polish school, where Polish was taught, and a scouts team. The Polish minority remained active despite repressions, a number of Poles were members of the Union of Poles in Germany.
