By December, the prince and the empress were seriously discussing Frederick’s proposal for the partition of Poland. Would Catherine agree to lower her demands for territorial cessions by a defeated Turkey in exchange for permanent territorial gains in Poland? Catherine pondered the question; savoring her military and naval victories, she was reluctant to compromise. After all, Russia was the only power actually at war with Turkey; it was she who was fighting and had defeated the Turks. Further, having invested so much effort and money in Polish affairs, she would have preferred, through Stanislaus, to make all Poland a permanent Russian satellite. As she considered her situation, however, she became more amenable. She realized that neither her ally Prussia nor an increasingly hostile Austria was likely to allow her to make sweeping Balkan acquisitions at Turkey’s expense. In the back of her mind, she feared that Austria and France might enter the war as Turkey’s allies; for months now, both Austria and France had been sending help in the form of money and military advisers to the confederates in Poland. Further, she realized that the deep permanent hatred between Orthodox and Catholic Poles was probably going to make Poland an endless military and financial drain. Finally, she knew that for many Russians, including leaders and believers of the Orthodox Church, bringing the Orthodox population of Poland under Russian protection would be enthusiastically welcomed, and that this would be sufficient to quiet those who had wanted more.
In January 1771, while Prince Henry was edging his way through the Russian Christmas and New Year, Austrian troops suddenly crossed the Carpathians and occupied an area in southern Poland. This news reached the empress and Prince Henry at a concert at the Winter Palace. Henry, hearing the news, shook his head and observed, “It seems that in Poland one only has to stoop and help oneself.” Catherine picked up his lead and replied, “Why shouldn’t we both take our share?” Henry reported this exchange to Frederick with the comment, “Although this was only a chance pleasantry, it is certain that it was not said for nothing and I do not doubt that it will be very possible for you to profit by this occasion.”
In March, soon after his brother returned to Berlin, Frederick wrote to Catherine suggesting that, in view of Austria’s aggression, perhaps it would be appropriate if Prussia and Russia simply followed her example and took what they wanted. In mid-May the Prussian minister in St. Petersburg reported to Berlin that the empress had consented to a partition of Poland.
A year of negotiation passed before agreement on partition could be reached with Austria. During this year the diplomatic focus was on Maria Theresa. Already alarmed by Russian victories in the Balkans and objecting particularly to any suggestion that the Turks should be replaced on the Danube by the Russians, the Austrian empress committed herself in July 1771 to a secret treaty with Turkey to come to the assistance of this ancient Muslim enemy of the Hapsburgs. Secrets have short lives, however, and when Frederick and Catherine learned of it, they ignored Austria and, on February 17, 1772, signed an agreement to partition Poland. Meanwhile, Maria Theresa’s son and co-ruler, Emperor Joseph II, was struggling to persuade his mother that it was in Austria’s interest to join Frederick and Catherine. This was an excruciating moment for the Austrian empress. She hated and despised these two monarchs; Frederick was a Protestant who had stolen Silesia; Catherine was a usurper who had taken lovers. Maria Theresa was a devout Catholic, and she shuddered at the idea of assisting in despoiling a neighboring Catholic state.
It took time to overcome these scruples, and her son worked hard to set her decision in a larger context than personal feelings. The Austrian empress faced a choice: either she maintained her recently signed treaty with Turkey and had to go to war with Russia with no help from any other European power, or she abandoned the Turks and joined Prussia and Russia in helping herself to another, larger slice of Poland. In the end, Maria Theresa abandoned the Turks. On August 5, 1772, Emperor Joseph II, on his mother’s behalf, added his signature to the agreement to partition Poland.
The three partitioning powers sent troops into their newly claimed territories and then demanded that a Polish Diet be called to ratify their aggression. In the summer of 1773, Stanislaus obediently summoned a Diet. Many Polish noblemen and Catholic churchmen refused to attend; some who came were arrested; others accepted bribes and remained silent. The rump Diet then transformed itself into a confederation that did not require a majority decision. In this way, on September 30, 1773, Poland signed the partition treaty formally ceding the land it had already lost.
