Note 51 — Chapter III · THE AUTONOMOUS CENTER IN POLAND AT ITS ZENITH (1501-1648)

After the incorporation of Mazovia into the Polish Empire, in 1526, Warsaw emerged from its obscurity and in the latter part of the sixteenth century became the capital of united Poland and Lithuania, taking the place of Cracow and Vilna.]
