In 1774 the Treaty of Kutschouk Kainardji was concluded with Turkey, by which the independence of the Mongol Tartars in the Crimea was acknowledged by the Sultan; Russia obtained the right of protection over all the Christian subjects of the Porte within a certain limit, and also the right of free navigation in all Turkish waters for trading vessels. This treaty firmly planted Russia on the northern coasts of the Black Sea.

In 1783 the Crimea was incorporated with Russia, and in 1787 Catherine visited the southern part of Russia as far as Kherson, on the Black Sea. Joseph II. of Austria, on hearing of her approach to his dominions, hastened to meet her, and together they journeyed through the Crimea, the Czarina unfolding to the Emperor both her own plans and those of Potemkin, her favourite, viz., to expel all the Turks from Europe, re-establish the old Empire of Greece, and place her younger grandson Constantine on the throne of Constantinople. Joseph fell in with her view, and it was hinted that something like a Western Empire should be also constituted and placed under the Austrian sway. In this way a division of the Ottoman Empire was contemplated between the two countries. This soon aroused the suspicions of Turkey, and war was again declared. But now it was two against one, and the fate of Turkey again seemed sealed.

William Pitt was the first statesman who directly opposed Russia and tendered assistance to Turkey against Russian encroaching power. His foreign policy of opposition to Russia has been followed more or less by generations of English Ministers. The Triple Alliance of England, Prussia, and Holland was formed by Pitt against the “Colossus of the North,” in order to preserve the balance of power in Europe, and the death of Joseph. II., saved Turkey again. Pitt, by means of this Alliance, demanded that a peace be made between Russia and Turkey on the status quo ante bellum, and threatened to maintain his demand by arms. The English people, however, cared very little about a Russian invasion of Turkey, while Catherine disregarded Pitt’s threats.

Soon after a peace between Russia and Turkey was concluded at Jassy, by which Turkey ceded Oczakow and the land between the Dnieper, Bug, and Dniester, containing several good harbours, and notably Odessa; the protectorate of Russia over Tiflis and Kartalinia was also recognized.

By the above-mentioned acquisitions she felt certain that very soon Constantinople would be in her hands. However, a nearer, and, in her opinion, a more important matter engaged her attention. In 1792 the new Constitution of Poland was drawn up by Ignaz Potocki, converting the Elective Monarchy into an hereditary one, the House of Saxony supplying a dynasty of kings. The Confederacy of Jargowitz, which was formed in opposition to this new Constitution, called in the help of Russia.

This now seemed to be a grand opportunity for Russia to finally annex Poland, because the deaths of Frederick the Great (1786) and Joseph (1790), and the French Revolution, which occupied the attention of all Western Europe, set the Czarina free from her most watchful rivals. A Russian army invaded Poland, and the new Constitution was repealed. Prussian troops also entered Poland under the pretence of suppressing Jacobinism, and Russia again found herself frustrated, and concluded a Second Partition (1793) with Prussia, by which she received Lithuania, Volhynin, and Podolia.

In 1795 the Polish nation rebelled, under the leadership of Xoscruscko, and this led to a Third Partition between Russia, Prussia, and Austria, and the former Power added 181,000 square miles, with 6,000,000 inhabitants, together with Curland, to her already vast dominions.

By this last Partition a road of aggression was open towards Sweden on the north-west, and towards Turkey on the south.

Many combined circumstances led Russia to assume an aggressive policy towards Turkey specially. Sweden, or rather Finland, was not of sufficient importance as a prey to the “northern bear”—a warmer climate was also wanted. Catherine had already discovered the mistaken policy of Peter the Great, who had spent all his energy in getting the strongholds of the Baltic in opposition to Charles XII. of Sweden. Russian sway on the Baltic meant a direct opposition from two great sea Powers, viz., England and Holland, whose interests would suffer thereby. A striking proof of the opposition was seen in the case of the Northern War.

The Partition of Poland produced another stray Power in the Baltic, to wit, Prussia.
