obwóds and powiats. There were eight voivodeships. On 7 March 1837, in the aftermath of the November Uprising earlier that decade, the administrative division was reformed once again, bringing Congress Poland closer to the structure of the Russian Empire, with the introduction of guberniyas (governorate, Polish spelling gubernia). In 1842 powiats were renamed okręgs, and obwóds were renamed powiats. In 1844 several governorates were merged with others, and some others renamed. Five governorates remained.

The 1867 reform, initiated after the failure of the January Uprising, was designed to tie the Congress Kingdom (now de facto the Vistulan Country) more tightly to the administration structure of the Russian Empire. It divided larger governorates into smaller ones. A new lower level entity, gmina, was introduced. The existing five governorates were restructuredinto 10. The 1912 reform created a new governorate—Kholm Governorate—from parts of the Sedlets and Lublin Governorates. It was split off from the Vistulan Country and made part of the Southwestern Krai of the Russian Empire.[15]

The sources are also unclear as to when Congress Poland (or Vistula land) officially ended; some argue it ended when the German and Austro-Hungarian occupying authorities assumed control;
