Babur dies in Agra, leaving his son and heir Humayun in power. Humayun proves to be possibly the weakest leader of the Mughal empire, with no real leadership qualities and an opium addiction. He and his three brothers fought for the throne. Because his father only established the empire 4 years earlier, he was left with no administration system in place. His attempt at administration was divided into four earthly categories- earth, fire, water, and air- so he grouped together sections that wouldn't have been put together otherwise. This was inefficient, and didn't last.
