In India, the Mughal Empire was one of the greatest empires ever. The Mughal Empire ruled hundreds of millions of people. India became united under one rule, and had very prosperous cultural and political years during the Mughal rule. There were many Muslim and Hindu kingdoms split all throughout India until the founders of the Mughal Empire came. There were some men such as Babar, grandson to the Great Asian conqueror Tamerlane and the conqueror Genghis Khan from the northern region of Ganges, river valley, who decided to take over Khyber, and eventually, all of India.
A dynasty is not called great because of its longevity,its greatness lies in how they influence and transforms the life of the people.The Mughal kings were not just conquerors,they were also patrons of arts,encouraged trade and ran an efficient administration. We now have many historical writings and miniature paintings as an information on how Mughals encouraged in all the matters and were also very frank in loose matters or in celebrations,but at the same time stable in the administrative work as an emperor.

So this was how Mughal Empire rose on its zenith...but there was also its decline which has another story.
