After world war-II the british lost its most of the colonies.One of them was India.British lost India in 1947.Then the british India was divided into two religious countries for muslims as pakistan and for Hindus as India.Then the problem raised was migration of people.Then the migration started taking place because after the divisions,people found themselves in the wrong place.Therefore most of Muslims started migrating to pakistan from India and most of the Hindus from Pakistan started migrating to India.
     Therefore the migration took place during the division of India.
