Historical studies of the Russian empire in upheaval in the first two decades of the twentieth century have tended to be animated by a narrow centralist bias or an equally narrow regional one. Although it is clear that the primary impulse for revolutionary situations in 1905 and 1917 resulted from events in St. Petersburg/Petrograd, a Russocentric approach to a society that was less than 50 percent Russian is surely inadequate. At the same time, studies of individual minority nationalities, however thorough, tend to view these groups in isolation. A comparative perspective, which could identify broader uniformities as well as local peculiarities, is usually lacking. In this article I shall present a synthesizing and comparative overview of the Revolution of 1905 in the Baltic Provinces and Finland. Although these areas constituted only 2 percent of the land area of the Russian empire and had less than 4 percent of its population in 1905,2 they were among the most modernized in the country, and their ethnic diversity and differing histories provide abundant material for a comparative case study.
