Partition—the rapid, uncoordinated, and bloody split between India and Pakistan after the Second World War—remains the central event of South Asian history. But 1947 wasn’t the only partition, according to historian and filmmaker Sam Dalrymple.

Sam, in his book Shattered Lands: Five Partitions and the Making of Modern Asia (William Collins, 2025), notes that “British India” once spanned all the way from the Arabian Peninsula to the border with Thailand, covering South Arabia, South Asia and Burma. Yet between 1937 and 1971, the region split into various different national entities, creating the countries and borders we see today.

Sam is a historian, filmmaker, and cofounder of Project Dastaan, a peacebuilding initiative that reconnects refugees displaced by the 1947 partition of India.
