Tolong jelaskan mengenai Vilna dari Liga Bangsa dalam bahasa melayu

After World War I, Poland and Lithuania both regained the independence that they had lost during the partitions of Poland in 1795. Though both countries shared centuries of common history in the Polish-Lithuanian Union and Polish-Lithuanian Commonwealth, rising Lithuanian nationalism prevented the recreation of the former federated state. The city of Vilna (Lithuanian Vilnius, Polish Wilno) was made the capital of Lithuania, despite being mainly Polish in ethnicity.

During the Polish-Soviet War in 1920, a Polish army took control of the city. Despite the Poles' claim to the city, the League chose to ask Poland to withdraw: the Poles did not. The city and its surroundings were proclaimed a separate state of Central Lithuania and on 20 February 1922 the local parliament passed the Unification Act and the city was incorporated into Poland as the capital of the Wilno Voivodship. Theoretically, British and French troops could have been asked to enforce the League's decision; however, France did not wish to antagonise Poland, which was seen as a possible ally in a future war against Germany, while the United Kingdom was not prepared to act alone. Both the United Kingdom and France also wished to have Poland as a 'buffer zone' between Europe and the possible threat from Communist Russia. Eventually, the League accepted Wilno as a Polish town on March 15 1923. Thus the Poles were able to keep it until Soviet invasion in 1939.

Lithuanian authorities declined to accept the Polish authority over Wilno and treated it as a constitutional capital. It wasn't until the 1938 ultimatum, when Lithuania resolved diplomatic relations with Poland and thus de facto accepted the borders of its neighbour.
