(Karaleўstva Pol'skae і Vjalіkae Knjastva Lіtoўskae)

b.   Historians date the change of the Polish capital from Krakow to Warsaw between 1595 and 1611, although Warsaw was not officially designated capital until 1793. The Commonwealth Sejm began meeting in Warsaw soon after the Union of Lublin and its rulers generally maintained their courts there, although coronations continued to take place in Krakow. The modern concept of a single capital city was to some extent inapplicable in the feudal and decentralized Commonwealth. Warsaw is described by some historians as the capital of the entire Commonwealth. Vilnius, the capital of the Grand Duchy, is sometimes called the second capital of the entity.
