Against a backdrop of communal tension, the protest triggered massive riots in Calcutta. More than 4,000 people lost their lives and 100,000 residents were left homeless in Calcutta within 72 hours. This violence sparked off further religious riots in the surrounding regions of Noakhali, Bihar, United Provinces (modern Uttar Pradesh), Punjab, and the North Western Frontier Province. These events sowed the seeds for the eventual Partition of India.
