After the death of Aurangzeb in 1707, the Mughal power weakened and by the second half of the 18th century, a new political power was emerging I.e. the British.
In 1600, the East India Company with the charter from Queen Elizabeth I of England got the sole right to trade in the East.
This charter was like a golden ticket to the company, with this they got no other competitor and could buy cheap goods and sell them at the good back in Europe (such enterprises are called Mercantile).
However, the charter failed to stop other European powers to enter the Eastern markets. English ships by then had crossed the Indian Ocean, Portuguese explored had established at the western coast, Dutchand the French followed by the 17th century.
All these companies were interested in buying the things from India which had big markets in Europe likefine cotton, silkand pepper, cloves, cardamom etc.
The high demandfor these goods, raise the price minimizing the profits. The only way was to reduce the competition, and for that, throughout the 17th and 18th century these powers kept fighting with each other.
Fortification of trade post started to carry on a profitable trade, which led to conflicts with local rulers, and thus the company was unable to separatetrade from politics.
