The partition of India had become unavoidable by 1947. This was due to the poison of communal division that had been introduced into India by the British with the connivance of Jinnah. During the Second World War, the British had put most of the leading Congress leaders in prison. The Muslim League under Jinnah had used the oportunity to cosy up witht he British to press the demand for Pakistan. The British also collaborated with Jinnah to impose new hurdles in the path to independence. As a result, the country became polarized along communal lines making partition inevitable.
