Nadezhda Krupskaya – revolutionary, educator, Lenin's partner. But was she merely the woman by his side, or was she a driving force behind the Bolshevik movement? This book sheds light on the life and influence of a woman who often stood in Lenin's shadow but played a decisive role in Soviet educational reform, party development, and Marxist ideology. From her early political awakening and years in exile to her key role in shaping the Soviet Union, Krupskaya's journey reveals the story of a visionary whose im-pact is still felt today. Oleg Sirokin presents a compelling portrait of a woman who helped shape the future of an entire nation—yet remained underestimated for far too long.
