Final answer:
The March Revolution was a spontaneous uprising leading to a provisional government aiming for democracy, while the Bolshevik Revolution was a planned socialist coup led by Lenin's Bolshevik Party, resulting in a socialist state and the withdrawal from WWI.
Step-by-step explanation:
The differences between the March Revolution and the Bolshevik Revolution in Russia are significant. The March Revolution, which took place in 1917, was a spontaneous uprising that led to the abdication of Tsar Nicholas II and the creation of a provisional government hoping to bring political reform and democracy.
During the March Revolution, near the end of the Tsarist reign, strikes and demonstrations burgeoned, notably in Petrograd. This unrest was fueled by food shortages, loss of life in World War I, and a desire for political change. Once the army sided with the protesters, the Tsar abdicated. However, the provisional government could not sustain power, and the Bolsheviks capitalized on continued discontent, promising "peace, land, and bread."
