Assalamulaikum,
I have made a list of topics which are extremely important. But am facing difficulty completing the list. Please provide your input.
1)The Arabs conquest of Sindh.
2)Causes of invasions of Arabs.
3)Expeditions of Muhammad Bin Qasim.
4)Mahmud Ghaznavi and his expeditions.
5)Causes of invasions of Mehmud.
6)Mohammad Ghori and his expeditions.
7)Iltutmish: Challenges, strategies, administration.
8)Balban: Mongol policy, Theory of Kingship.
9)Alauddin Khilji: Challenges and achievements, administration.
10)Muhammad bin tughlaq: mixture of opposites, administration.
11)Firoz shah tughlaq: administration.
12)Impact of Islam during Delhi Sultanate.
13)Architecture under the Delhi Sultanate.
14)The Mongol policy of the Delhi Sultanate.

Now, can someone guide me about the must-have knowledge/topics of the Mughals? I mean those topics which cannot be skipped at any cost. I know some of them like the Din-e-elahi and Mansabdari system of Akbar, but i need a complete list. Architecture of Mughals, causes of failure is also important. some important sufis and ulemas etc.
Please provide anything that I might have missed.
