plebiscite was held on 11 July 1920. There was a out with the population wishing to remain with Germany. Further plebiscites were held in Eupen-Malmedy and Neutral Moresnet. On 20 September 1920, the League of Nations allotted these territories to Belgium. These latter plebiscites were followed by a boundary commission in 1922, followed by the new Belgian-German border being recognized by the German Government on 15 December 1923. The transfer of the Hultschin area, of Silesia, to Czechoslovakia was completed on 3 February 1921. Following the implementation of the treaty, Upper Silesia was initially governed by Britain, France, and Italy. Between 1919 and 1921, three major outbreaks of violence took place between German and Polish civilians, resulting in German and Polish military forces also becoming involved. In March 1921, the Inter-Allied Commission held the Upper Silesia plebiscite, which was peaceful despite the previous violence. The plebiscite resulted in the population voting for the province to remain part of Germany. Following the vote, the League of Nations debated the future of the province. In 1922, Upper Silesia was partitioned: Oppeln, in the north-west, remained with Germany while Silesia Province, in the south-east, was transferred to Poland. Memel remained under the authority of the League of Nations, with a French Armed Forces garrison, until January 1923. On 9 January 1923, the Lithuanian Army invaded the territory during the Klaipėda Revolt. The French garrison withdrew, and in February the Allies agreed to attach Memel as an "autonomous territory" to Lithuania. On 8 May 1924, after negotiations between the Lithuanian Government and the Conference of Ambassadors and action by the League of Nations, the annexation of Memel was ratified. Lithuania accepted the Memel Statute, a power-sharing arrangement to protect non-Lithuanians in the territory and its autonomous status while responsibility for the territory remained with the great powers. The League of Nations mediated between the Germans and Lithuanians on a local level, helping the power-sharing arrangement last until 1939.
