In the same year Louis Napoleon made an end to the French Republic by the notorious Coup d'État. This gave great satisfaction to the czar who was heard to remark: "France has set an evil example; she will now set a good one. I have faith in the conduct of Louis Napoleon." The new emperor of France did not seem to appreciate this condescension, or else he showed gross ingratitude when France and Austria, without even consulting Nicholas, settled some troubles in Turkey. The czar sent Menzikoff as special envoy to Constantinople to demand a new treaty whereby Russia's rights as Protector of the Greek Christians should be recognized. Supported as he was by France, the sultan refused. Nicholas then had a plain talk with Sir Hamilton Seymour, the British Minister at St. Petersburg, wherein he revealed his designs upon Turkey. As to Constantinople, he said, he might establish himself there as a trustee, but not as a proprietor. Sir Hamilton, as in duty bound, notified his government, and England hastened to join France in opposing Russia.

Pretending that all he wanted was a recognition of his rights, Nicholas, on the 3d of July, 1853, sent an army under Gortchakof across the Pruth. At this an allied British-French fleet took up a position near the threatened point, but did not cross the Straits, which would have been a violation of the treaty. Nicholas stormed; he declared that "This was a threat" and would lead to complications. Austria proposed a conference at which Russia, Great Britain, France, Austria and Prussia assisted. It seemed as if peace would be secured, when the sultan demanded that the Russian forces should withdraw, whereupon Admiral Nakhimof, on the 30th of November, 1853, destroyed the Turkish fleet at Sinopé. The British-French fleet then sailed into the Black Sea, and the Russian ships sought shelter in the ports.

In January, 1854, Napoleon III made a last attempt at maintaining peace, but Nicholas was thoroughly angry at the publication of Seymour's dispatches, claiming that the conversation with the British Minister was entitled to secrecy as between "a friend and a gentleman." Austria and Prussia resented the contempt which the czar had expressed for them, and on the 10th of April England and France entered into an offensive-defensive alliance. Ten days later Austria and Prussia arrived at a written agreement providing for the possibility that the Russians should attack Austria or cross the Balkans. Nicholas had aroused all Europe against him.

The Russian fleet was unable to cope with that of the allies, and thus condemned to inactivity in the ports. After heroic efforts, the Russians were compelled to raise the siege of Silistria, and to retire from the Danube, while Austria occupied the evacuated territory. But Nicholas was dismayed when, after a conference on July 21, 1854, the allied commanders resolved to attack the Crimea. Russia was unprepared. It was the assault upon Russia's vaunted "holy soil," which gave a severe blow to the arbiter of Europe, at home as well as abroad. Still with clogged energy the Russians worked to construct defenses. On the 14th of September 500 troopships landed the allied armies, and on the 20th, the Battle of the Alma opened the road to Sebastopol. The port of Balaclava was captured by the allies, and three bloody battles were fought, at Balaclava on the 25th of October, at Inkermann on the 5th of November, and at Eupatoria on the 17th of February, 1855.

It seemed as if the knowledge that an enemy was in Russia, aroused the Russians from a torpor. Pamphlets and other publications denouncing the government in withering terms, seemed to spring up from the pavement. "Arise, Oh Russia!" says one unknown writer, "Devoured by enemies, ruined by slavery, shamefully oppressed by the stupidity of tchinovnik and spies, awaken from thy long sleep of ignorance and apathy! We have been kept in bondage long enough by the successors of the Tartar khans. Arise! and stand erect and calm before the throne of the despot; demand of him a reckoning for the national misfortunes. Tell him boldly that his throne is not the altar of God, and that God has not condemned us to be slaves forever."

The feeling among his people was not unknown to Nicholas. Whatever may be said of him, he was not weakling, fool, or hypocrite, and it was no disgrace that he felt as if the ground were giving way under his feet. He was upright and sincere, and had lived up to his convictions. There is no doubt that when these convictions grew dim, his strength vanished. He was heard to exclaim "My successor may do what he will: I cannot change." The sincerity of this man of iron showed in his losing his courage when doubts arose. Life ceased to have any value for him. One day, in February, 1855, while suffering from a severe cold, he went out without his overcoat. To the physician who tried to restrain him, he said: "You have done your duty; now let me do mine!" A serious illness followed, and he sent for his successor to whom he gave some instructions. As a message to his people, and a last cry for sympathy, he dictated the dispatch "The emperor is dying," which was sent to all the large towns of Russia. On the 19th of March, 1855, Nicholas I was dead.

Under his directions wealthy merchants were classified as "chief citizens," which procured for them exemption from poll-tax, conscription, and corporal punishment. They might take part in the assessment of real estate, and were eligible to the offices to which members of the first class were entitled. The same privilege was extended to all who were entitled to the degree of Master of Arts, and free-born and qualified artists. It was he who built the first railway in Russia, by drawing a straight line between Moscow and St. Petersburg. He also joined the Volga and the Don by a canal. His reign is also noted for the progress of Russian literature. The works of Ivan Tourguénief are known throughout the civilized world.
