Prepared in early 1920, the plebiscite took place on 11 July 1920 and was conducted by German authorities under Inter-Allied control.[7]
The plebiscite reported that most voters had selected East Prussia over Poland (over 97% in the Allenstein Plebiscite Area and 92% in the Marienwerder Plebiscite Area[8]). As a result, most of the territories in question remained in the Free State of Prussia, and therefore, in Germany.
