Explanation:

Lenin continued his work as a revolutionary. He moved to St. Petersburg where he quickly became a leader among the Marxists. He constantly had to hide from the police and government officials as spies were everywhere. Eventually, Lenin created his own group of Marxists called the Bolsheviks.
In 1897, Lenin was arrested and exiled to Siberia for three years. Upon his return in 1900 he continued to foster revolution and push Marxism. However, he was banned from St. Petersburg and was under the watchful eye of the police. He spent much of his time over the next several years in Western Europe where he wrote communist papers and planned for the coming revolution.
