Grabski’s treasury and currency reform

After 123 years of partitions, the economy was obsolete and war-damaged. Many reforms were soon carried out, including Władysław Grabski’s treasury and currency reform which was of key importance for the economy and prevented hyperinflation. A new currency was established: the Polish zloty. 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.
