The Mughal Empire, Shahan-e-Gurkhani, Shahan-e-Mughal, Sultanate-e-Mughliya, Daulat-e-Mughliya (Persian: شاهان گورکانی‎ Shāhān-e Gūrkānī; Urdu: مغلیہ سلطنت; self-designation: گوركانى Gūrkānī ),‎ or Mogul (also Moghul) Empire in traditional English usage, was an imperial power from the Indian Subcontinent. The Mughal emperors were direct descendants of Genghis Khan through Chagatai Khan and Timur. The Mughal Empire began in 1526; at the height of their power in the late 17th and early 18th centuries, they controlled most of the Indian Subcontinent—extending from Bengal in the east to Balochistan in the west, Kashmir in the north to the Kaveri basin in the south. According to "Babur-Nama", Kazakh tribal aristocracy along with number of other Turkic soldiers participated actively in the campaign of Babur, which made great influence over the development of Mughal Empire. Its population at that time has been estimated as between 110 and 150 million, over a territory of more than 3.2 million square kilometres (1.2 million square miles).
