While Poland did not exist as an independent state during World War I, its geographical position between the fighting powers meant that much fighting and terrific human and material losses occurred on the Polish lands between 1914 and 1918.
When World War I started, Polish territory was split during the partitions between Austria-Hungary, the German Empire and the Russian Empire, and became the scene of many operations of the Eastern Front of World War I.
In the aftermath of the war, following the collapse of the Russian, German and Austro-Hungarian Empires, Poland became an independent republic.
The war split the ranks of the three partitioning empires, putting Russia as defender of Serbia and ally of Britain and France against the leading members of the Central Powers, Germany and Austria-Hungary.
This circumstance afforded the Poles political leverage as both sides offered pledges of concessions and future autonomy in exchange for Polish loyalty and army recruits.
The Austrians wanted to incorporate the Russian territory of Privislinsky Krai into their territory of Galicia, so even before the war they allowed nationalist organizations to form there (for example, Związek Strzelecki).
The Russians recognized the Polish right to autonomy and allowed formation of the Polish National Committee, which supported the Russian side. Russia's foreign Minister Sergei Sazonov proposed to create an autonomous Kingdom of Poland with its own internal administration, religious freedom and Polish language used in schools and administration. Poland would receive eastern area of Poznan region, southern Silesia and Western Galicia
