As recently as 1928, a vast swath of Asia stretching from the Red Sea to the borders of Thailand was bound together under a single imperial banner, an entity known officially as the "Indian Empire" or, more simply, as the Raj. It was the British Empire's crown jewel, home to a quarter of the world's population. In the span of just fifty years, that empire shattered. Five partitions tore it apart, carving it into twelve modern nations, including not only India, Pakistan, and Bangladesh, but also Burma, the United Arab Emirates, and Qatar.

In vivid and compulsively readable prose, Sam Dalrymple presents, for the first time, the whole story of how the Indian Empire was unmade. It’s a story of maps being redrawn in boardrooms and on battlefields, bumbling politicians in London and idealist revolutionaries in Delhi, kings in remote palaces and ordinary citizens swept up in wars and mass migrations. It is a history of ambition and betrayal, of forgotten wars and unlikely alliances, of borders carved with ink and fire. And it has left behind a legacy of exile and division.

It began in 1937, when Burma was carved out of India, to devastating result. The partition of the Arabian Peninsula started the same year with the separation of Aden and was completed in 1947 with the transfer of the Gulf States. Also in 1947 was the “Great Partition,” culminating in the largest forced migration in history and the creation of Pakistan, swiftly followed by the partition of Princely India. Finally, in 1971, the fledgling nation of Pakistan was itself torn apart, and Bangladesh was born.

Based on deep archival research, previously untranslated sources, and hundreds of interviews in English, Hindi, Urdu, Bengali, Punjabi, Konyak, Arabic, and Burmese, Shattered Lands is an utterly gripping history that offers a new understanding of modern South Asia—one that brings to light the continuing legacy of empire.
