Some of the disputed regions handled by the Conference included Cieszyn Silesia (between Poland and Czechoslovakia), the Vilnius Region (between Poland and Lithuania), the Klaipėda Region (between Germany and Lithuania) and the Corfu Incident (between Italy and Greece). One of its major territorial decisions was made on 15 March 1923, in recognizing the eastern borders of Poland created following the Polish–Soviet War of 1920. The Conference also recognized Polish sovereignty over the Vilnius region and Eastern Galicia.
