In what came to be called the First Partition of Poland, the crumbling state lost almost a third of its territory and more than a third of its population. Russia’s share was the largest in territory, 36,000 square miles, comprising all of eastern Poland as far as the Dnieper River and the whole course of the river Dvina flowing north toward the Baltic. This area, known as White Russia (now a part of the independent nation of Belorussia) had a population of 1,800,000 people, primarily of Russian stock with Russian identity, traditions, and religion. Prussia’s slice of Poland was the smallest, both in area and population: 13,000 square miles, with 600,000 people, predominantly German and Protestant. Frederick was satisfied, at least at that moment. By acquiring the Baltic enclaves of West Prussia and Polish Pomerania, he achieved his goal of uniting his kingdom geographically, stitching the separated province of East Prussia onto Brandenburg, Silesia, and other Prussian territories in Germany. Austria took a substantial piece of southern Poland: 27,000 square miles, including the greater part of Galicia. Maria Theresa acquired the largest number of new subjects: 2,700,000 Poles, overwhelmingly Catholic. A few Poles resisted this aggression, but against the strength of three major powers, they had little success. England, France, Spain, Sweden, and the pope condemned the partition, but no European state was prepared to go to war on behalf of Poland.
Catherine’s intervention in Poland was successful. She had returned Russia’s frontier to the great trade route of the Dnieper. Two million Orthodox believers could profess their faith unhindered. But she still had important objectives in her war with Turkey. The fact that Russia’s western frontier had been brought back to the Dnieper did not mean the opening of that great water route to the Black Sea, because the Turks still controlled the estuary where the river flowed into the sea. Catherine meant to free this river mouth. The war with Turkey continued.
The year 1771 had produced a disappointment on the battlefields. On the Danube, Russian generals had been unable to follow up their victories of 1770. Even though General Vasily Dolgoruky had stormed into the Crimea and overrun the peninsula, this had not inclined the sultan to make peace. Three years of stalemate and frustration followed. Not until the end of 1773 did Russian prospects brighten. In December, Sultan Mustapha III died and was succeeded by his brother, Abdul Hamid. The new sultan, recognizing the unprofitability as well as the danger of continuing the war, decided to end it. Catherine prompted him with a new offensive on the Danube. In June 1774, Rumyantsev crossed the Danube with fifty-five thousand men. On June 9, fifty miles south of the river, a night bayonet attack by eight thousand Russians on forty thousand Turks broke the Turkish lines and led to a crushing Russian victory at Kozludzhi. The grand vizier, fearing that nothing could stop the Russians from reaching Constantinople, sued for peace. Rumyantsev opened direct negotiations in the field, and he and the grand vizier agreed to terms. On July 10, 1774, in an obscure Bulgarian village, the Treaty of Kuchuk Kainardzhi was signed. Rumyantsev immediately sent his son to St. Petersburg with the news, and on July 23, Catherine hurried out of a concert to receive it.
The treaty brought Russia greater gains than she had dared to hope for. Catherine traded her conquests on the Danube for more important acquisitions on the Black Sea coast. The Balkan provinces of Moldavia and Wallachia were restored to Turkey. In exchange, Catherine gained the transfer to Russia of Azov, Taganrog, and Kerch, which provided unfettered access to the Black Sea. Farther west, she acquired the southern delta of the Dnieper River, and the mouth of the river itself, giving her empire another vital outlet to the Black Sea. Although the west bank of the river’s broad estuary still retained the massive Turkish fortress at Ochakov, the Russians now had a fort and port at Kinburn on the east bank, and the estuary was large enough to permit Russian commercial navigation and the unhindered construction of Russian warships. The peace terms also included the ending of the sultan’s political sovereignty over the Crimean Peninsula, where a Tatar khanate under Turkish protection had existed for centuries. The Crimean Tatars were now declared to be independent of Turkey. Everyone realized that the independence of the Crimea was unlikely to last; indeed, nine years later, Catherine was to annex the peninsula outright.
