The gripping untold story of a terrorist leader whose death would catapult his brother -- Lenin -- to revolution. In 1886, Alexander Ulyanov, a brilliant biology student, joined a small group of students at St. Petersburg University to plot the assassination of Russia's tsar. Known as "Second First March" for the date of their action, this group failed disastrously in their mission, and its leaders, Alexander included, were executed. History has largely forgotten Alexander, but for the most important consequence of his execution: his younger brother, Vladimir, went on to lead the October Revolution of 1917 and head the new Soviet government under his revolutionary pseudonym "Lenin." Probing the Ulyanov family archives, historian Philip Pomper uncovers Alexander's transformation from ascetic student to terrorist, and the impact his fate had on Lenin. Vividly portraying the psychological dynamics of a family that would change history, Lenin's Brother is a perspective-changing glimpse into Lenin's formative years -- and his subsequent behavior as a revolutionary.
