In depth
The Partitions (zabory) were the three divisions of Poland between Russia, Prussia, and Austria in 1772, 1793, and 1795. After the Third Partition, Poland ceased to exist as a sovereign state for 123 years, until the establishment of the Second Polish Republic in 1918.
The Partitions created three distinct administrative regions: the Russian Partition (Warsaw, Lublin, Białystok), the Prussian Partition (Poznań, Bydgoszcz, Gdańsk), and the Austrian Partition (Kraków, Lwów, Tarnów — also known as Galicia).
For CBD cases, the Partitions matter because: (1) records from each partition are in different languages (Russian, German, Latin) and held in different archives; (2) Polish citizenship did not exist during the partitions, so ancestors who emigrated before 1918 were not Polish citizens — they were Russian, Prussian, or Austrian subjects.
