ENThe seizure of Vilnius Region by Gen. Lucjan Żeligowski, development of the structures of Central Lithuania, elections to the Vilnius Parliament and a resolution of Vilnius Region to join the Polish Republic created a new quality in the bilateral Polish-Lithuanian relations. The seizure of Vilnius Region was a success of Warsaw. The Lithuanian state consequently avoided the establishment of diplomatic relations with Poland, while the geopolitical position of the Second Polish Republic made it necessary for Poland to have Lithuania as an ally supporting Polish efforts to form a common front against threats in the region.
