Conditions in the predominant agricultural sector kept deteriorating between 1929 and 1939, which resulted in rural unrest and a progressive radicalization of the Polish peasant movement that became increasingly inclined toward militant anti-state activities. It was firmly repressed by the authorities. According to Norman Davies, the failures of the Sanation regime (combined with the objective economic realities) caused a radicalization of the Polish masses by the end of the 1930s, but he warns against drawing parallels with the incomparably more repressive regimes of Nazi Germany or the Stalinist Soviet Union.
