Lenin was one of the leading political figures and revolutionary thinkers of the 20th century, who masterminded the Bolshevik take-over of power in Russia in 1917, and was the architect and first head of the USSR.

Vladimir Ilich Ulyanov was born in Simbirsk on the Volga River on 22 April 1870 into a well-educated family. He excelled at school and went on to study law. At university, he was exposed to radical thinking, and his views were also influenced by the execution of his elder brother, a member of a revolutionary group.

Expelled from university for his radical policies, Lenin completed his law degree as an external student in 1891. He moved to St Petersburg and became a professional revolutionary. Like many of his contemporaries, he was arrested and exiled to Siberia, where he married Nadezhda Krupskaya. After his Siberian exile, Lenin – the pseudonym he adopted in 1901 – spent most of the subsequent decade and a half in western Europe, where he emerged as a prominent figure in the international revolutionary movement and became the leader of the ‘Bolshevik’ faction of the Russian Social Democratic Worker’s Party.
