Free City of Danzig and World War II Main article: Free City of Danzig An aerial view of the historic city centre around 1920 When Poland regained its independence after World War I with access to the sea as promised by the Allies on the basis of Woodrow Wilson's "Fourteen Points", the Poles hoped the city's harbour would also become part of Poland.[121] However, in the end – since Germans formed a majority in the city, with Poles being a minority[122] – the city was not placed under Polish sovereignty. Instead, in accordance with the terms of the Treaty of Versailles, it became the Free City of Danzig, an independent state under the auspices of the League of Nations with its external affairs largely under Polish control.
