Answer:
One reason the Bolsheviks were able to seize power in October 1917 was the weakness of the Provisional Government. Led by Alexander Kerensky, the government made the unpopular decision to continue fighting in the First World War, which caused more hardship and chaos in Russia. It also failed to solve land disputes or food shortages and had to share power with the Petrograd Soviet, making it hard to pass reforms (K). These problems meant that people lost trust in the government. Workers, soldiers and peasants were angry and ready for change. Many began to look towards more radical parties, such as the Bolsheviks, who promised to make citizens' lives better. Therefore, the failure of the Provisional Government created the conditions for revolution by October, as it lost the support of the people and allowed the Bolsheviks to gain strength (SOC).
Another key reason was Lenin’s leadership, which helped the Bolsheviks grow in popularity. When Lenin returned to Russia in April 1917, he immediately set out the April Theses, calling for “peace, bread and land” and an end to the Provisional Government. Lenin’s slogans appealed to ordinary Russians. He also persuaded his party to carry out a revolution in October, before the planned elections could reduce their influence (K). Lenin provided clear direction and helped the Bolsheviks stand out from other socialist groups. His timing and decisiveness were crucial, as he convinced the Party to act when the Provisional Government was at its weakest. Therefore, Lenin’s leadership was essential, as it turned the Bolsheviks into a powerful and organised revolutionary force (SOC).
A final reason was the strength and organisation of the Bolsheviks, especially in Petrograd. Under the leadership of Trotsky, they gained control of the Petrograd Soviet and used the Red Guards to seize key locations such as railway stations, post offices and the Winter Palace. This was done with minimal resistance (K). Due to their careful planning and growing support, the Bolsheviks were able to take power quickly and efficiently. Their military strength, propaganda and strategy made the seizure of power almost inevitable once the government’s weaknesses became clear. (SOC). Therefore, the Bolsheviks’ planning and control of force meant they could turn popular support into political power, completing their takeover in October.
