In 1801 Paul I was assassinated and the Lithuania Governorate was divided into the Lithuania-Vilna Governorate and the Lithuania-Grodno Governorate by his successor, Alexander I of Russia.

The governorate was formed in 1796, in the aftermath of the final partition of Polish-Lithuanian Commonwealth, and originally known as Slonim Governorate, but that only existed until December 12, 1796, when Paul I merged it with Vilna Governorate to form Lithuania Governorate.
