In 1918, various proposals emerged defining the division of Upper Silesia. At the Paris Peace Conference, a commission for Polish affairs was created to prepare proposals for the Polish borders. In its first two proposals (on 27 March 1919 and of 7 May 1919), most of the future province was ceded to Poland, together with the region of Oppeln. That was not accepted by the Big Four, however, and British Prime Minister David Lloyd George successfully suggested for a plebiscite to be organised.
