The East India Company established its base in Bengal during the 18th century, marking a significant shift in the company's role in India. Here are the key points regarding the base of the East India Company in Bengal:

Trade in Bengal:
- The East India Company initially focused on trade in Bengal, particularly in textiles, silk, and spices.
- The Company's presence in Bengal grew rapidly due to the region's prosperous economy and strategic location.

Establishment of Fort William:

- Over time, Fort William became the center of the Company's operations in Bengal and played a crucial role in the Company's expansion in the region.

Conflict with Nawabs:
- The growing power of the East India Company in Bengal led to conflicts with the Nawabs, who were the local rulers of the region.

Revenue Collection:

In conclusion, the establishment of the East India Company's base in Bengal was a crucial step in the Company's expansion in India and the eventual colonization of the country. The Company's growing influence in Bengal paved the way for British dominance in the region and set the stage for the British Raj in India.
