The Czechoslovak state had a (financial) monopoly on tobacco, salt, artificial sweeteners, and explosive substances between the two world wars. There were also several large national enterprises.
In the 1930s, cartelisation took place with state approval (Act No. 141/1933 Sb.z. a n.) and 'the grain monopoly' was established in 1934 (Decree No. 137/1934 Sb.z. a n.). The paper examines the various roles of state monopolies as major sources of state finances, important elements in national security, or anti-crisis measures.
