Official encouragement by the Polish state played a secondary role in the exodus. While there were demonstrations and protests and occasional violence against Germans, they were at a local level, and officials were quick to point out that they were a backlash against former discrimination against Poles. There were other demonstrations when Germans showed disloyalty during the Polish-Bolshevik war as the Red Army announced the return to the prewar borders of 1914. As many as 80% of Germans emigrated more or less voluntarily.
