Method adopted in the non-cooperation movement in 1921:

The non-cooperation movement, launched by Mahatma Gandhi in 1921, aimed to unite Indians in their struggle for independence from British rule. The movement focused on nonviolent resistance and passive resistance, encouraging Indians to boycott British institutions, goods, and services. The method adopted in the non-cooperation movement included various strategies and tactics.

Boycott of British institutions:
- Indians were urged to boycott government offices, courts, and educational institutions that were run by the British.
- This aimed to undermine the legitimacy and authority of the British administration and create a sense of self-governance among Indians.

Boycott of British goods:
- Indians were encouraged to boycott foreign goods, especially British-manufactured textiles, and instead support locally-made products.
- This aimed to weaken the economic power of the British and promote Indian self-sufficiency.

Withdrawal from government positions:
- Indian civil servants and professionals were called upon to resign from their government positions as a sign of protest against British rule.
- This aimed to create a void in the administration and disrupt the functioning of British institutions.

Peaceful protests and demonstrations:
- Nonviolent protests, such as processions, strikes, and public meetings, were organized to express dissent and demand independence.
- These peaceful demonstrations aimed to showcase the unity and determination of the Indian people.

Use of traditional Indian practices:
- Gandhi emphasized the use of traditional Indian practices, such as spinning and weaving cloth (khadi), to promote self-reliance and economic independence.
- The spinning wheel became a powerful symbol of resistance against British economic exploitation.

Mass civil disobedience:
- Indians were encouraged to engage in acts of civil disobedience, such as non-payment of taxes and non-cooperation with British authorities.
- This aimed to disrupt the functioning of British rule and demonstrate the power of the Indian masses.

Conclusion:
The non-cooperation movement in 1921 employed various methods to challenge British rule in India. Through the boycott of British institutions and goods, withdrawal from government positions, peaceful protests, the use of traditional practices, and acts of civil disobedience, the movement aimed to weaken British authority and promote Indian self-governance. These strategies highlighted the power of nonviolent resistance and played a significant role in India's struggle for independence.
