The book about Ermak, the conqueror of Siberia, belongs to the pen of the recognized classic of the historical and biographical genre Ruslan Grigorievich Skrynnikov. Based on a painstaking analysis of extensive documentary material, it recreates the grandiose panorama of the expedition of the Russian Cossacks led by ataman Ermak Timofeevich (1582-1585), which resulted in the accession of Siberia to the Russian state.
