India has had invaders from Central Asia since ancient times, what made the Muslim invasions different is that unlike the preceding invaders who assimilated into the prevalent social system, the successful Muslim conquerors retained their Islamic identity and created new legal and administrative systems that challenged and usually in many cases superseded the existing systems of social conduct and ethics, even influencing the non-Muslim rivals and common masses to a large extent, though the non-Muslim population was left to their own laws and customs. They also introduced new cultural codes that in some ways were very different from the existing cultural codes. This led to the rise of a new Indian culture which was mixed in nature, different from ancient Indian culture. Some of the departments during this period were-1) A-1: Ariz-i-Mumalik- Head of the military department
2) B-4: Diwan-i- Risalat- It dealt with the religious matter
3) C-5: Diwan-i-Insa- It dealt with the state correspondence
4) D-2: Barid-i-Mumalik- Head of state New Agency
5) E-3: Wakil-i-Dar- Controller of the royal household.
