The Coupland plan was formed by-
Reginald Coupland

 The Coupland Plan was a proposal for the future of British India that was put forward by Reginald Coupland, a British historian and academic. The plan was published in 1943, in a book titled India: A Restatement.

The Coupland Plan proposed that British India should be divided into three zones:

  • A Muslim zone, comprising the North-West Frontier Province, Baluchistan, Sind, and the Punjab.
  • A Hindu zone, comprising the rest of British India, excluding Assam.
  • A Tribal zone, comprising Assam and the hill areas of the North-East.

The Coupland Plan was not adopted by the British government, but it did influence the thinking of the policymakers who were responsible for the partition of India in 1947.

Reginald Coupland was born in 1884 and educated at Oxford University. He was a professor of history at Oxford from 1920 to 1947. He was also a member of the Indian Statutory Commission, which was set up in 1930 to investigate the future of British India.

The Coupland Plan was controversial at the time it was published. Some people argued that it would lead to the break-up of India, while others argued that it was the only way to ensure the future stability of the country. The plan was ultimately rejected by the British government, but it did influence the thinking of the policymakers who were responsible for the partition of India in 1947.
