Why were Petrograd’s factories important in the February Revolution?

Correct answer: They became centres of workers’ strikes

Petrograd was a major industrial centre, and its factories brought together large numbers of workers who faced low wages, difficult conditions, food shortages and wartime hardship. Because workers were concentrated in factory districts, news and protest could spread quickly from one workplace to another. Strikes began in factories and developed into wider demonstrations against the Tsarist government. Thus option A is correct: the factories became centres of workers’ strikes and political mobilisation. Options B, C and D misidentify the nature of these places. They were industrial workplaces, not palaces, farms or courts. Their importance came from the organisation and collective strength of industrial workers.
