CBBC Newsround : Partition

This was called the Partition of India.

As a result, many families were split up and forced to leave behind their homes for good. Around 12 million people became refugees.

Many families have been unable to go back to the homes that their relatives had to leave behind.

Now, 10-year-old Sumayyah, 11-year-old Shubhashukla and nine-year-old Kamolpriya are on the mission of their lives to find out what happened to their families.

What will they learn? Will they track down their relatives' old houses?
