In the 1850s Russia was a poor agrarian society with a rapidly growing population. Almost 90 percent of the population lived off the land, and serfdom was still the basic social institution. Then the Crimean War of 1853 to 1856 arose from the breakdown of the balance of power established at the Congress of Vienna, European competition over influence in the Middle East, and Russian desires to expand into European territories held by the Ottoman Empire. France and Great Britain, aided by Sardinia and the Ottoman Empire, inflicted a humiliating defeat on Russia.

Russia’s military defeat showed that it had fallen behind the industrializing nations of western Europe. Moreover, the war had caused hardship and raised the specter of massive peasant rebellion. Military disaster thus forced the new tsar, Alexander II (r. 1855–1881), and his ministers along the path of rapid social change and general modernization.

The first and greatest of the reforms was the freeing of the serfs in 1861. The emancipated peasants received, on average, about half of the land, which was to be collectively owned by peasant villages. The prices for the land were high, and collective ownership limited the possibilities of agricultural improvement and migration to urban areas. Thus the effects of the reform were limited. More successful was reform of the legal system, which established independent courts and equality before the law. The government also relaxed censorship and partially liberalized policies toward Russian Jews.

Russia’s greatest strides toward modernization were economic rather than political. Rapid, government-subsidized railroad construction to 1880 enabled agricultural Russia to export grain and thus earn money for further industrialization. Russia began seizing territory in far eastern Siberia, on the border with China; in Central Asia, north of Afghanistan; and in the Islamic lands of the Caucasus.

In 1881 an anarchist assassinated Alexander II, and the reform era came to an abrupt end. Political modernization remained frozen until 1905, but economic modernization sped forward in the massive industrial surge of the 1890s. The key leader was Sergei Witte (suhr-GAY VIH-tuh), the energetic minister of finance. Under Witte’s leadership, the government doubled Russia’s railroad network by the end of the century and promoted Russian industry with high protective tariffs.

By 1900 Russia was catching up with western Europe and expanding its empire in Asia. By 1903 Russia had established a sphere of influence in Chinese Manchuria and was eyeing northern Korea. When the protests of equally imperialistic Japan were ignored, the Japanese launched a surprise attack on Russian forces in Manchuria in February 1904. After Japan scored repeated victories Russia was forced in September 1905 to accept a humiliating defeat.

Military disaster in East Asia brought political upheaval at home. On January 22, 1905, workers peacefully protesting for improved working conditions and higher wages were attacked by the tsar’s troops outside the Winter Palace. This event, known as Bloody Sunday, set off a wave of strikes, peasant uprisings, and troop mutinies across Russia. The revolutionary surge culminated in October 1905 in a paralyzing general strike, which forced the government to capitulate. The tsar, Nicholas II (r. 1894–1917), issued the October Manifesto, which granted full civil rights and promised a popularly elected Duma (DOO-muh; parliament) with real legislative power.

Under the new constitution, Nicholas II retained great powers and the Duma had only limited authority. The middle-class liberals, the largest group in the newly elected Duma, were badly disappointed, and efforts to cooperate with the tsar’s ministers soon broke down. In 1907 Nicholas II and his reactionary advisers rewrote the electoral law so as to increase greatly the weight of the propertied classes. On the eve of World War I, Russia was partially modernized, a conservative constitutional monarchy with an agrarian but industrializing economy.
