The attempt made by a young student to assassinate Alexander II, on April 4, 1866, was seized upon by the Czar and his advisers as an excuse for instituting a policy of terrible reaction. The most repressive measures were taken against the Intelligentsia and all the liberal reforms which had been introduced were practically destroyed. It was impossible to restore serfdom, of course, but the condition of the peasants without land was even worse than if they had remained serfs. Excessive taxation, heavy redemption charges, famine, crop failures, and other ills drove the people to desperation. Large numbers of students espoused the cause of the peasants and a new popular literature appeared in which the sufferings of the people were portrayed with fervor and passion. In 1868-69 there were numerous demonstrations and riots by way of protest against the reactionary policy of the government. It was at this time that Michael Bakunin, from his exile in Switzerland, conspired with Nechaiev to bring about a great uprising of the peasants, through the Society for the Liberation of the People. Bakunin advised the students to leave the universities and to go among the people to teach them and, at the same time, arouse them to revolt. It was at this time, too, that Nicholas Tchaykovsky and his friends, the famous Circle of Tchaykovsky, began to distribute among students in all parts of the Empire books dealing with the condition of the peasants and proposing remedies therefor. This work greatly influenced the young Intelligentsia, but the immediate results among the peasants were not very encouraging. Even the return from Switzerland, by order of the government, of hundreds of students who were disciples of Bakunin and Peter Lavrov did not produce any great success. Very soon a new organization appeared. The remnant of the Circle Tchaykovsky, together with some followers of Bakunin, formed a society called the Land and Freedom Society. This society, which was destined to exert a marked influence upon revolutionary Russia, was the most ambitious revolutionary effort Russia had known. The society had a constitution and a carefully worked out program. It had one special group to carry on propaganda among students; another to agitate among the peasants; and a third to employ armed force against the government and against those guilty of treachery toward the society. The basis of the society was the conviction that Russia needed an economic revolution; that only an economic revolution, starting with the producers, could overthrow Czarism and establish the ideal state of society.
