What events led to the Russian Revolution?

The Russian Revolution was primarily driven by widespread discontent with the autocratic rule of Tsar Nicholas II, exacerbated by military failures in World War I, economic hardship, and food shortages. The 1905 Revolution had already highlighted the demands for political reform, but disillusionment grew as conditions worsened. The February Revolution in 1917 was sparked by mass protests and strikes, leading to the abdication of the Tsar. This was followed by the October Revolution, where the Bolsheviks, led by Lenin, seized power, promising peace, land, and bread.
