The Maurya empire is most like this kingdom. They both have a select group of loyal nobles. As your advisor, I think you should bring up the fact that their supervision is wearing them out. Say that when they team with you, you will split the work. Plus, both of you will have a lot of power. Additionally, you should mention the idea of you guys creating a tax system together. You could tell him that you will have tax workers that collect taxes from every subject, and that money goes in you guys' pockets!

Scenario #1:

Rose Eisenmenger Period 2

For example, Chandragupta set up a bureaucracy which is a system of having government workers watch over your subjects and carry out the government rules and regulations. He did this to maintain order in a large area.
Maurya packet pg. 236

Another example from my cause and effect worksheet on ISN pg. 73 is, the effect of Chandragupta creating a bureaucracy was his wealth increasing by a lot.
