Partition of India: My memories
19 August 2014 Last updated at 20:46 BST
In August 1947 India gained independence from the British and split into two separate countries - the secular state of India, dominated by Hindus, and Muslim Pakistan.
Millions of people were forced to leave their homes because of inter-religious violence.
Muslims trekked to Pakistan and Hindus travelled to India.
Kuldip Nayar was one of the many who had to make a desperate journey in search of safety. He spoke to Witness about his memories of that time.
Witness is a World Service radio programme of the stories of our times told by the people who were there.
