What problem occurred in India when British control ended?

The problem of Partition caused the largest level of
challenges when British control ended in India.  The largest two religious groups in
India were those of the Hindu faith and those of the Islamic faith.  There were Hindus
and Muslims in nearly every village and city in India.  The arbitrary line that was
drawn to divide India and Pakistan heightened tensions between both groups and
instigated communal riots between both groups in a setting where the government was
unable to fully address such challenges.  When busloads of Hindus were burned by Muslims
who were seeking revenge for trains of Muslims burned by Hindus, one could say that this
was a major problem for India.  At the same time, the idea of the diversity of India
posed another hurdle for the new nation.  India was a nation with more than Hindus and
Muslims.  So many groups were unified with a common enemy in the British.  The Anglo
departure created a vacuum where these different groups started to view one another with
skepticism.
