From the end of 1759 to the end of 1761, the firmness of the Russian Empress was the one constraining political force that held together the heterogeneous, incessantly jarring elements of the anti-Prussian combination. From the Russian point of view, her greatness as a stateswoman consisted of her steady appreciation of Russian interests and her determination to promote them against all obstacles. She insisted throughout that the King of Prussia must be rendered harmless to his neighbors for the future and that the only way to do so was to reduce him to the rank of a Prince-Elector.
