The colonial government used brutal repressive measures to suppress the Civil Disobedience Movement. It arrested thousands of peaceful satyagrahis, imposed harsh laws, and used police violence. Leaders including Gandhiji were jailed. The government refused to concede key demands such as reducing revenue rates, which led to widespread resentment and eventual weakening of the movement.

The question asks specifically about suppression of the Civil Disobedience Movement. Note that the source passages don't give detailed methods of suppression directly, but examiners expect students to mention arrests, repression, jailing of leaders, and refusal to meet demands — all implied by the passages (e.g., movement being "called off," government using "repression"). Keep the answer concise and factual. Avoid listing social group participation, which is a different aspect.
