On 16 January 1816 the administrative division was reformed, with the departments being replaced with more traditionally Polish voivodeships (of which there were eight), obwóds and powiats. On 7 March 1837, in the aftermath of the November Uprising earlier that decade, the administrative division was reformed again, bringing Congress Poland closer to the structure of the Russian Empire, with the introduction of guberniyas (governorate, Polish spelling ""). In 1842 the powiats were renamed okręgs, and the obwóds were renamed powiats. In 1844 several governorates were merged with others, and some others renamed; five governorates remained.
