The American Civil War caused new problems for Indian weavers. Indian weavers could not get sufficient supply of raw cotton of good quality. The Americans stopped supplying raw cotton to Britain due to the Civil War.

The correct answer is option 'A' - The American Civil War.

Explanation:
The American Civil War, which took place from 1861 to 1865, had a significant impact on the Indian weaving industry. Here's a detailed explanation of how this war caused new problems for Indian weavers:

1. Impact on cotton production: The American Civil War disrupted cotton production in the United States, which was the largest supplier of raw cotton to India. As a result, there was a shortage of raw materials for Indian weavers, who heavily relied on American cotton imports.

2. Increase in cotton prices: The disruption in the supply of raw cotton led to a significant increase in its prices. Indian weavers had to pay higher prices for cotton, affecting their profit margins. This made it difficult for them to sustain their businesses.

3. Competition from British manufacturers: During the American Civil War, British manufacturers turned to India to meet their demand for cotton goods due to the disruption in American cotton supply. This led to an increase in British imports of cotton textiles into India, creating tough competition for Indian weavers.

4. Decline in demand for Indian textiles: As British imports increased, the demand for Indian textiles declined. The British manufacturers could offer cheaper and more accessible alternatives to Indian textiles, which negatively impacted the sales of Indian weavers.

5. Economic hardships for weavers: With the decline in demand and increase in competition, Indian weavers faced economic hardships. Many weavers lost their livelihoods, and poverty among the weaving community increased.

6. Social implications: The decline of the weaving industry had significant social implications. Weavers, who were once respected and had a stable income, now faced poverty and social marginalization. This led to a decline in the status and living conditions of the weaving community.

Overall, the American Civil War caused new problems for Indian weavers by disrupting the supply of raw materials, increasing competition from British manufacturers, and leading to a decline in demand for Indian textiles. These factors resulted in economic hardships and social implications for the weaving community.
