The collection "The Revolution of 1905-1907. in the national regions of Russia" was written by a group of researchers from the Institute of History of the USSR Academy of Sciences with the involvement of a number of workers - specialists in the history of individual peoples. Work on the compilation of the collection began even before the war with Nazi Germany. The war delayed the printing of the prepared book, and then it was necessary to replenish the articles with newly published materials. Therefore, the authors again revised their works, replenished them with new data in accordance with the published literature and new sources.
