Q: Why was Vilnius a contentious city between Poland and Lithuania?

Vilnius was contentious due to its mixed ethnic population and historical ties to both Poland and Lithuania.

Q: What was Józef Piłsudski's proposal for a Polish-Lithuanian federation?

Józef Piłsudski proposed renewing the Polish-Lithuanian Commonwealth as a federation led by Poland, including Ukraine and Belarus. This idea was opposed by some Polish political factions and rejected by Lithuania, which prioritized historical arguments over contemporary nationality concepts, leading to further tensions.

Q: How did Lithuania's agreement with Bolshevik Russia affect its neutrality?

Lithuania's agreement with Bolshevik Russia, which allowed Soviet troops to pass through its territory to attack Poland, complicated its claim of neutrality in the Polish-Soviet War. This deal was seen by Poland as an anti-Polish alliance, though Lithuania viewed it as a desperate move to recover Vilnius as its capital.

The Polish Army's victories in 1920, particularly at Warsaw and the Neiman River, shifted the balance of power, leading to the occupation of Vilnius.
