In the Austrian Partition, Polish culture was openly cultivated, and in the Prussian Partition, there were high levels of education and living standards, but the Russian Partition remained of primary importance for the Polish nation and its aspirations. About 15.5 million Polish-speakers lived in the territories most densely populated by Poles: the western part of the Russian Partition, the Prussian Partition and the western Austrian Partition. Ethnically Polish settlement spread over a large area further to the east, including its greatest concentration in the Vilnius Region, amounted to only over 20% of that number.
