the arrival of last Viceroy of India Lord Mountbatten, communal riots (Hindu-Muslim ) broke in Bengal and slowly spread to different parts. For your information The All India Muslim League demanded for creation of a new nation by the name of Pakistan for the Muslim Community, but their demands were initially rejected by the British GOVERNMENT.When the riots broke out, The British sent Lord Mountbatten to deal with the situation as the government was about to transfer the power to Indians but when he ARRIVED here in India, he realized that Cabinet MISSION wouldn’t work here and these riots could only be stopped by the creation of a new Nation by the name of Pakistan.BUTBoth PANDIT Jawaharlal Nehru and Jinnah wanted to be the first Prime Minister of INDIA but if Nehru would have let Jinnah to be the first PM then these riots wouldn’t had been broken as everyone knew that Jinnah was suffering from TB and he would die in about 6 months but he was adamant that he wanted to be the first PM and thus the riots broke out and Lord Mountbatten designed the plan for PARTITION OF INDIA and India was divided on Communal Grounds.
