It was the fortune of the Russian tsarina—Catherine the Great—to appreciate the real weakness of both Turkey and Poland and to turn her neighbors' distress to the profit of her own country.
[Sidenote: Catherine's Interference in Poland]
No sooner had Catherine secured the Russian crown and by her inactivity permitted Frederick the Great to bring the Seven Years' War to a successful issue, than the death of Augustus III, elector of Saxony and king of Poland, gave her an opportunity to interfere in Polish affairs. She was not content with the Saxon line which was more or less under Austrian influence, and, with the astute aid of Frederick, she induced the Polish nobles to elect one of her own courtiers and favorites, Stanislaus Poniatowski, who thus in 1764 became the last king of an independent Poland.
With the accession of Stanislaus, the predominance of Russia was fully established in Poland. Russia entered into an execrable agreement with Prussia and Austria to uphold the anarchical constitution of the unhappy and victimized country. When patriotic Poles made efforts—as they now frequently did—to reform their government, to abolish the liberum veto, and to strengthen the state, they found their attempts thwarted by the allies either by force of arms or by bribes of money. The racial animosities and the religious differences within Poland afforded sufficient pretexts for the intervention of the neighboring Powers, especially Prussia and Russia.
A popular insurrection of Polish Catholics against the intolerable meddling of foreigners was crushed by the troops of Catherine, with the single result that the Russians, in pursuing some fleeing insurgents across the southern frontier, violated Turkish territory and precipitated a war between the Ottoman Empire and Russia.
[Sidenote: Catherine's War with the Turks, 1768-1774]
This Turkish War lasted from 1768 to 1774. The Ottoman government was profoundly alarmed by the Russian foreign policy, believing that the intrigues in Poland would end in the annexation of that state to Russia and the consequent upsetting of the balance of power in the East, and that, Poland once being disposed of, the turn of Turkey would come next. The Turks, moreover, were egged on by the French government, which, anxious also to preserve the balance of power and to defend the liberties of Poland, was too financially embarrassed itself to undertake a great war against Prussia and Russia.
This war between Russia and Turkey fully confirmed the belief that the power of the latter was waning. The Ottoman troops, badly armed and badly led, suffered a series of reverses. The Russians again occupied Azov, which Peter the Great had been compelled to relinquish; they overran Moldavia and Wallachia; they seized Bucharest; and they seemed likely to cross the Danube. Catherine went so far as to fan a revolt among the Greek subjects of the sultan.
[Sidenote: Treaty of Kuchuk Kainarji (1774): Russia on the Black Sea]
At length, in 1774, the treaty of Kuchuk Kainarji was concluded between the belligerents. It was most important in marking the southern extension of Russia. By its provisions, (1) Turkey formally ceded Azov and adjacent territory to Russia and renounced sovereignty over all land north of the Black Sea; (2) Turkey recovered Wallachia, Moldavia, and Greece, on condition that they should be better governed; (3) Russia obtained the right of free navigation for her merchant ships in Turkish waters; and (4) Russia was recognized as the protector of certain churches in the city of Constantinople.
