Viceroy’s House in Delhi was the glorious home of the British rulers of India. For 6 months in 1947, Lord Mountbatten assumed the post of the last Viceroy, charged with returning India to the Indians. He lived upstairs together with his wife and daughter. Downstairs lived their 5,000 Hindu, Muslim and Sikh servants. As the political elite took their seats upstairs to wrangle over the birth of independent India, conflict erupted throughout the House. In a moment of history that demands to be wider understood, a catastrophic decision was taken that continues to shake our world.
