After the Mountbatten Plan and the Indian Independence Act of 1947, two separate independent countries, India and Pakistan, came into existence. Around 1.5 crore people from both the countries migrated by leaving their houses and properties; about two to five lakh Muslims and Hindus were killed. India faced the following problems:
1) The problem of refugee-settlement arose due to the migration.
2) Land boundaries on the eastern and western side of India had to be demarcated.
3) Military forces, debts and credits, public services, and the arrangement of civil servants and administrative staff had to be reorganised.
