Answer:
The correct answer is 1. The Bolshevik Revolution of 1917 was a major turning point in history because Russia became the first nation with a Communist economic system.
Step-by-step explanation:
The Russian Revolution was a series of uprisings that reached its peak in 1917. During this revolution the Tsarist rule was replaced by a temporary government that led to the establishment of the Soviet Union, that lasted until its fall in 1991.
There were two phases in the Russian Revolution. The first period was the February Revolution in 1917, when Nicholas II of Russia was replaced by a democratic government. During the second period, the October Revolution, the Bolshevik-inspired communists wanted to set up a temporary government.
One of the reasons for the outbreak of the February Revolution was the lack of food and dissatisfaction with the country's role during the First World War. During February a protest turned into a battle with the townspeople battling police and soldiers. The majority of Petrograd troops joined the revolution and as a result Tsar Nicholas II was forced to resign from his monarchy.
Between February and October 1917 anarchists and Bolsheviks attempted to spark the revolution. In July the Bolshevik military division, the large Bolshevik workers' division and the Petrograd anarchists tried to create a civil uprising in Petograd, but this was unsuccessful.
The leader of the October Revolution was Lenin who accepted Karl Marx's ideology. This is how communism really began. Unlike the February Revolution the October Revolution was planned in detail. On November 7, 1917 came the collapse of the temporary government under Aleksandr Kerensky by the Lenin revolutionaries. A liberal democratic government turned into a single communism and the revolution came to an end.
After the Russian Revolution the Russian Civil War began.
