Emperor Humayun (full title: Al-Sultan al-'Azam wal Khaqan al-Mukarram, Jam-i-Sultanat-i-haqiqi wa Majazi, Sayyid al-Salatin, Abu'l Muzaffar Nasir ud-din Muhammad Humayun Padshah Ghazi, Zillu'llah) (March 17, 1508 – March 4, 1556) (OS March 7, 1508-OS February 22, 1556) was the second Mughal Emperor who ruled modern 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 250 million acres (1,000,000 km2).
He succeeded his father in India in 1530, while his half-brother Kamran Mirza, who was to become a rather bitter rival, obtained the sovereignty of Kabul and Lahore, the more northern parts of their father's empire. He originally ascended the throne at the age of 22 and was somewhat inexperienced when he came to power.
Humayun lost his Indian territories to the Afghan Sultan, Sher Shah Suri, and, with Persian aid, regained them fifteen years later. Humayun's return from Persia, accompanied by a large retinue of Persian noblemen, signalled an important change in Mughal Court culture, as the Central Asian origins of the dynasty were largely overshadowed by the influences of Persian art, architecture, language and literature. Subsequently, in a very short time, Humayun was able to expand the Empire further, leaving a substantial legacy for his son, Akbar the Great (Akbar-e-Azam). (more)
