Following his escape and during his exile into Western Europe Trotsky Continued to agitate for world revolution. This made him very unpopular with many governments and resulted in him being continually deported. By early 1917 he had ended up in New York City, USA. Then in February 1917 a democratic liberal government overthrew the Tsar and attempted to establish a democracy. Learning of this, Trotsky immediately set out on a German ship bound for Russia. However, his ship was seized by British troops and imprisoned in Canada. Yet, he was soon freed when the Russian Government -under pressure from the socialists- demanded his return. Trotsky arrived in Petrograd (St. Petersburg) on May 17 but did not join the Bolsheviks right away (even though he agreed with many of their ideas at this point.)
At first Trotsky joined a regional Petrograd party and was even elected a member of the All-Russian Central Executive Committee. Following a failed Bolshevik seizure of power in April, Trotsky was arrested along with other Communists but released 40 days later. Meanwhile, he joined the Bolshevik party and was elected chairman of the Supreme Soviet. Here he supported Lenin and his plan for an immediate armed uprising. After seizing power on November 7-8 Trotsky led Communist forces against the counterattack from the recently deposed democratic government. However, the Bolsheviks had yet to form a functional government and with the exception of the Left SRs no other political party supported them. In fact, many were downright hostile and would make certain that a Bolshevik rise to power would not be easy.
