Construction of the sea port in Gdynia
In the two-decade interwar period, Polish society was very diverse, with the Poles making just 64% of the population and the rest ethnic minorities. After 123 years of partitions, the economy was obsolete and war-damaged. Many reforms were soon carried out, including an agrarian reform. In 1926, the construction of a Polish Baltic sea port in Gdynia began. Once the crisis of the late 1930s was over, work on the Central Industrial Region (COP) started, including a number of industrial plants.
