Excerpts from Books and Wikipedia
"The Peace of Paris of 1763 did not put an end to France’s suffering. In the following year, the collapse of her once-dominant influence in eastern Europe was revealed by the election of Stanislas II Poniatowski as King of Poland. By imposing her own candidate-and superannuated lover to boot-the new Tsarina, Catherine II, demonstrated that Poland was now a Russian satellite." [Blanning: Pursuit of Glory, p. 588]
