Now had the long-wished-for opportunity arrived for Russia to carry into effect on Turkey her long-cherished designs. Diebitch, a Russian general, crossed the Balkans, and soon captured Adrianople; while Paskevitch took Kars and Erzeroom in Asia.

These successes resulted in the Treaty of Adrianople (1829), between Russia and Turkey. By the treaty[[53]] Russia gave back almost all her conquests to Turkey, only retaining the ports of Anapa and Poti, on the eastern coast of the Black Sea, and the Protectorate powers of the Czar over the Danubian Principalities were confirmed and extended. In return Turkey acquiesced in all the provisions of the London Conference.

This made Greece practically an independent state.

Nicholas pursued the policy of Alexander I. with regard to the Asiatic boundaries, and successfully carried on a war with Persia from 1826 to 1828 which was terminated by the Treaty of Turkmantchai (1828), Russia receiving the provinces of Erivan and Nakhitcheven. This was the period of the expansion of Russia, and the first appearance of Russia as a real rival of Great Britain.

Reviewing the general policy of Nicholas the reader cannot help being struck with the skilful manner and clever system by which the Czar carried out his plans.

Before his reign the Russian attacks were all made particularly in the south-west and south-east direction, viz., the Danubian territory, and Armenia; but on his accession he began to attack from a more southerly direction even than Turkey, viz., Greece, whom he assisted in rebellion against her Turkish oppressors. From 1826–1828 he attacked in a south-easterly quarter, viz., Armenia and Persia, at the same time occupying Adrianople and threatening Constantinople. Finally, to complete his plans, he struck a fatal blow at the heart of Turkey, viz., its capital, Constantinople, in 1833, with the Treaty of Unkiar Skelessi, by which Turkey was practically made a vassal of Russia.

This treaty exercised a great influence upon foreign powers. For Russia by it would have obtained actual possession not only of the Black Sea but also of its only entrance, the Dardanelles, which thus would have become a fortified Russian outpost.

Turkey now was in a very precarious state. She was almost past the aid of any earthly powers. But luckily two doctors stepped into the breach, namely, England and France, and, after a course of treatment, the following protocol was indited by the Pentarchy of Powers: “That ships of war have at all times been prohibited from entering the Channel of Constantinople, viz., by the Straits of the Dardanelles and of the Black Sea.”

Reshid Pacha had performed for Turkey great internal reforms, but, unfortunately, he was exiled through a Court intrigue. This proved a great blow to Turkish politics.

Thus Turkey began to decline again; and, as John Bright said in an able speech at Manchester (1854), “Turkey is a decaying nation;” and Cobden on the same occasion said, “Turkey is a decaying country, and the Turks cannot be permanently maintained as a ruling Power in Europe.” The Czar himself said that “a sick man is dying,” referring to Turkey, in his remarkable conversation with Sir Hamilton Seymour on January 28, 1853.
