Explanation:
The Second Civil Disobedience Movement, also known as the Salt Satyagraha, was actually started by Mahatma Gandhi in 1930, not 1932. It was a significant campaign in the Indian independence movement against British rule.

Here is a detailed explanation of the Second Civil Disobedience Movement:

1. Background:
- The Indian National Congress, under the leadership of Mahatma Gandhi, had been advocating for independence from British rule since its inception.
- The first Civil Disobedience Movement took place in 1920-1922, as a nonviolent protest against the repressive Rowlatt Act and other oppressive policies of the British government.
- After a period of relative calm, Gandhi decided to launch another major movement to further press for independence.

2. The Salt Satyagraha:
- On March 12, 1930, Mahatma Gandhi embarked on the famous Dandi March, a 240-mile journey from Sabarmati Ashram to the coastal village of Dandi in Gujarat.
- The purpose of this march was to protest against the British monopoly on salt production and the imposition of a salt tax, which heavily burdened the Indian population.
- Gandhi, along with his followers, collected salt from the seawater at Dandi, openly defying the British salt laws.
- This act of civil disobedience inspired millions of Indians to join the movement, as they began manufacturing salt in their own communities and disregarding the British regulations.

3. Nationwide Protests:
- The Salt Satyagraha quickly spread throughout India, with people from all walks of life participating in acts of civil disobedience.
- People boycotted British goods, picketed liquor shops, and violated other British laws and regulations.
- The movement gained momentum as more and more people joined in, including women who actively participated in protests and demonstrations.

4. Repression and Mass Arrests:
- The British government responded to the civil disobedience movement with force, using tear gas, lathi charges, and arrests to suppress the protesters.
- Thousands of people, including Mahatma Gandhi, were arrested and imprisoned.
- Despite the repression, the movement continued to gather support and remained nonviolent in its approach.

5. Impact and Significance:
- The Salt Satyagraha played a crucial role in mobilizing the masses and raising awareness about the oppressive nature of British rule.
- It showcased the power of nonviolent resistance and civil disobedience as effective tools for achieving political goals.
- The movement also led to the Round Table Conferences in London, where Indian leaders demanded greater self-governance and ultimately laid the foundation for India's independence.

In conclusion, the Second Civil Disobedience Movement, also known as the Salt Satyagraha, was started by Mahatma Gandhi in 1930. It was a significant protest against the British salt laws and played a crucial role in the Indian independence movement.
