Yogita Ingle 5 years, 7 months ago

The East India Company appointed gomasthas to supervise weavers in India to establish a more direct control over the weavers, free of the existing traders and brokers in the cloth trade.
The Gomasthas were the paid servants who supervised the weavers,collected supplies and examined the quality of cloth.
The gomasthas ensured that all management and control of the cloth industry came under the British.
This helped in eliminating competition, controlling costs and ensuring regular supplies of cotton and silk.
