The imar branch's doctrine node (tier 4); its prerequisite is Endowment.
The doctrine choice is exclusive
The moment you know one doctrine node, another branch's doctrine can no longer be taken. If you research nizam, you can never open the harp and muhafaza branches' doctrine nodes for the rest of that match — the choice is one-time (Research and the tech tree).
You see a rival's doctrine: even though your own tree is fully visible, of a rival's you see only the doctrine they have taken — in the badge next to their name on the score strip. The rest of their research stays hidden.
What it unlocks
It unlocks Divan — a unique building, only one of which can be built per empire, that shortens revolt duration and adds score (Divan).
What it keeps unlocking
Knowing nizam is also the prerequisite for researching the mastery node Law — you reach the imar branch's mastery only by choosing this doctrine.
