the mughal rule was called to be the golden age because during the rule of mughal it provided us with many benefits like political, economical, technological, administrative and cultural .mughals made our country stable.(the area of india which was under the control of mughals at that time.)mughals gave us many strong administrative rules which helps to make the country stable. mughals made the military power more powerful it developed the technology it provided us with the beautiful art and craft of the mughals. at the region of mughals no external power dared to invade india(the area under mughals which where now in india).
i hope that this will help u.
