Humayun's Tomb by akshayachauhan

Nasir ud-din Muhammad Humayun (Persian: نصیر الدین محمد همایون‎; OS 7 March 1508 AD – OS 17 January 1556 AD) was the second Mughal Emperor who ruled a large territory consisting of what is now Afghanistan, Pakistan, and parts of northern India from 1530–1540 and again from 1555–1556. Like his father, Babur, he lost his kingdom early, but with Persian aid, he eventually regained an even larger one. On the eve of his death in 1556, the Mughal empire spanned almost one million square kilometers. via 500px http://j.mp/1fYpXo8
