The one great political fact of Russia has been the autocracy. The degree of control which the autocratic Czars exercised unopposed over their subjects marks an important difference between the political development of Russia and that of the countries of Western Europe. At an early period the Czars had transformed the nobility into a body of state officials, thus at a blow depriving them of any real powers, apart from the will of the Crown, and making them serve the interests of the state. In this way the nobles, or the landed aristocracy, became the main source from which the members of the bureaucracy were recruited. The lack of a middle class of any real size and influence, which could play a part in the demand for political rights, explains in a measure the strength of the autocratic powers.[5] The autocracy in turn has been largely dependent upon its servant, the bureaucracy. To such an extent has the Russian government been the expression of the will and interests of this all-powerful body as to justify Leroy-Beaulieu's designation of Russia as the "Bureaucratic State". Thus the autocracy, the nobility-bureaucracy and the church have been the dominating forces in the economic, social and political life of Russia. In the light of this analysis, the political struggles that have been so conspicuous a feature of Russian life during the last half of the 19th century become an accompaniment as well as an expression of the progressive development of Russia towards modern economic, social and political institutions. Russian liberalism,--largely revolutionary because of the denial of even elementary rights, such as the freedom of person, of speech, of the press and of meeting,--rights which were secured to Englishmen through the Magna Charta--has had the serious task not only of securing these rights but at the same time of creating in Russia the conditions of modern civilization. For the twenty years in which its spirit ruled, during the reign of Alexander II, the reforms begun under its influence amounted to a veritable revolution. The economic, social, political and juridical reforms of this epoch generated new forces and began the modernization of Russia. These reforms encountered the formidable opposition of the nobility and the church and finally of the autocracy, when the latter felt that its position was gradually being undermined, especially by the demand for a constitution. With the assassination of Alexander II, the liberal era was brought to a close, and a reaction was ushered in which has lasted to our day.
