Kiev Voivodeship
The Commonwealth lost control of the province as early as 1648, during the Khmelnytsky Uprising. In the Treaty of Hadiach (1658), the Duchy of Ruthenia was created out of Czernihow Voivodship, Kiev Voivodeship and Bracław Voivodeship. The idea however was quickly abandoned, and after the Truce of Andrusovo (1667), Czernihow Voivodeship was annexed by the Tsardom of Russia.
