The Great Depression brought low prices for farmers and unemployment for workers. Social tensions increased, including rising antisemitism. A major economic transformation and multi-year state plan to achieve national industrial development, as embodied in the Central Industrial Region initiative launched in 1936, was led by Minister Eugeniusz Kwiatkowski. Motivated primarily by the need for a native arms industry, the initiative was in progress at the time of the outbreak of World War II. Kwiatkowski was also the main architect of the earlier Gdynia seaport project.
