Humayun, the son of Babur and the second Mughal ruler, reigned in Agra from 1530 to 1540 and then in Delhi from 1555 to 1556. Until now, his numerous achievements, including winning back the throne of Hindustan, have not been well recorded. The Planetary King follows Humayun’s travels and campaigns during the political and social disturbances of the early 16th century. It delves into Humayun’s extraordinary social and intellectual life; demystifies his magico-scientific world view, draws attention to his deep involvement with literature, poetry, painting, architecture, mathematics, astronomy, astrology, occultism and extraordinary inventions, and offers a new analysis of Humayun’s mausoleum as the posthumous sum of his visions and dreams.

The book accompanies the new site museum at Humayun’s tomb created by the Aga Khan Trust for Culture upon the culmination of two decades of conservation work on the World Heritage Site.
