Final answer:
The strategy to manufacture Indian goods domestically during the swadeshi movement was adopted to promote self-sufficiency and resist British economic exploitation in support of the Indian independence movement.
Step-by-step explanation:
The Indians decided to use the strategy of promoting the manufacture of Indian goods at home, and especially homespun cloth, as a form of non-violent protest against British rule with the aim of promoting self-sufficiency and resisting economic exploitation. By boycotting British goods, they aimed to resist economic exploitation by the British and instead support the local economy. This was part of the broader struggle for Indian independence, asserting control over one's own resources and industries as a fundamental aspect of self-rule or swaraj.
