1. The East India Company obtained rights to trade in India from the Mughal Emperor through a firman. This enabled them to obtain a foothold in India from which they could gradually expand power. They then set out to defeat local rulers in the South and Bengal. Their victory in Bengal was particularly significant as it enabled them to obtain the diwani of Bengal through which they could loot the revenue of Bengal.

He disallowed the prevailing practice under which kings could adopt a son and make him the heir.
