The document summarizes the partition of Bengal in 1905 and the reactions to it. It was partitioned for administrative reasons due to its large population and area. This benefited Muslims by making them the majority in East Bengal and opening new political and economic opportunities. However, Hindus strongly opposed the partition as it undermined their dominant social position and threatened their control of trade, government services, and the legal system. Their uprising turned violent and pressured the British to cancel the partition in 1911.
