Answer 2

Answer:

In 1600s the British East India company came to Gujarat and established their first factory at Surat. After, their trade spread all over India. They were opposed by ruler of Bengal Siraj-ud-duala. They fought first battle in India. After, the Battle of Plassey and Buxar , they slowly started to conquer other regions of India. The Britishers introduced many policies in India that acted as slow poision for Indian rulers. They conspire against the Indians ruler and slowly-slowly ruled over India with small army. Actually, the Britishers were able to rule India only due to their diplomatic policies which were actually a conspiracy.
