his is what I have gathered. The Bolsheviks were majorily the proletariat(poor people). They were tired of the Great War. They wanted out. They were tired of insufficient food. They were unhappy with the nobility owning the majority of the land. The Great War was eating up resources that Russia was having difficulty coming up with. Transportation was frequently down or very ify for the civilians because of the war effort. The troops needed food, and the men who farmed were many of at war. Food resources were often pushed to straining point. Heating was often just above freezing even for the middle class. You need fuel for heat. Troops need fuel for planes, trains, cars, etc. Living conditions were still poor despite reforms in the 1905 revolution. The military was suffering badly in the last decade or so. This was in the Russo-Japanese War which killed 400,000 Russian troops. Czar Nicholas was loosing support. The people were growing more and more restless. No heat, little food, upset military means ideal conditions for revolution. The Czar and a bit lower down were still being somewhat brutal which was a bad tactic. The military was transitioning to the proletariat's side. The majority party for the people were the Bolsheviks. The people's cry was "Peace! Land! Bread!". The Bolsheviks were the majority. They wanted a socialist state. The mensheviks were moderates who wanted a constitutional monarchy with a figurehead king. The Bolsheviks didn't fully win until 1920 after a civil war. The Bolsheviks were known as the REDS and the Mensheviks were known as the WHITES. The whites were more for the czar but for much reform by something like stripping him of much power but keeping him as figurehead. It reached near breaking point in early 1917. International Women's day gave the women an excuse to protest for food. Soon the men joined. Protest soon turned worse. Shots were fired. Bread riots started. The military decided to be on their own people's side. The situation deteriorated that czar Nicholas abdicated. His brother Mikhail refused. The Duma (equiv. of parliment) took that as abdication. For a few short months the Duma put up a government. Republican. They would continue the war. The people and Bolsheviks had enough. They planned a suprise. They took over in one night, seizing power stations, mail, communications, train depots, etc. The opposing side, the Mensheviks, were somewhat scattered and were not fully unified. They didn't agree on anything except that they didn't want the Bolsheviks taking control. The Bolsheviks had single goal that everyone was on. Peace! Bread! Land! It also helped that the Bolsheviks were backed by American bankers for all their weapons. I've heard that without that that the WHITES would have one. The Bolsheviks had a majority, they had a common goal, they had the supplies.
