How did britain manage to control the whole of india?

Question

there were so many people , so how did they manage it overseas

Answer 1

Britain managed to control the whole of India by using the
DIVIDE and RULE policy
The British establishment of the East India Company in West Bengal was the turning point in India's Colonial history

Answer 2

well first of all, it wasnt overseas.
the east india company adminstered india in the begining before it became the property of the british empire. all administration was done in the country itself.
they followed the policy of divide and rule. they also had extensively racist policies and controlled the masses by widespread, cruel & violent repression.
they also introduced new technologies and flooded our markets (classic capitalists!)
and so they controlled us for more than 100 years

god bless the revolution that came
