Russian Revolution Timeline

Response:
Three events that I'd consider to be the "turning points" in the progression of the revolution are Lenin returns from exile, War Communism, and the Great Purge. 

First of all, Lenin returns from exile set as the primary ignition for the revolution against the czar. His return had spread the message of 'Peace, bread, and land', which appealed to all those who were tired of war and the weak government that couldn't take care of them. Upon this event, the revolutionaries were inspired potently and therefore could eventually take official action to crush down the czar; it gave them power and strength to finally fight for their rights. Hence, this event had led to certain influential others such as protests against the czar, the emergence of the Bolsheviks, the treaty of Brest-Litovsk, etc. In short, Lenin's return was indeed the turning point in the first stages of the Russian Revolution. 

Second of all, War Communism can also be considered a turning point in the revolution because it was the first policy that ensured the Bolsheviks' power over the citizens. The policy had magnificently changed Russia economically, and greatly declined the population; it had purged almost all of the White factors so that Russia could be safely be under one solid control (the Reds/the Bolsheviks). Additionally, this turning point of event later led to other policies or ideals that deprived the citizens in order to serve the government. 

Last but not least, the Great Purge was also a turning point in the Russian Revolution because it had eliminated all forces that could conspire against Stalin. This wasn't just  the turning point in the Russian Revolution, but also in world history for it had caused many global disputes about communism and dictatorship. This turning point had led to Russia's decline in population, total control over the citizens' private lives and needs - due to the changing of photographs or historical facts, etc. This event would later inspire other communist nations to absolutely control and strain their citizens, promoting the power of only one person; hence, the profits would also come to certain things depending on that person's will.
