Throughout many Islamic nations, a sultan, shah or raja may reign, but it is the ministers, or viziers that rule in his name. The Sirdars' Divan thus is a national project that has the following characteristics:
- a vizierialty has an effect on happiness
- your people's happiness increases whenever you destroy enemy shipping and aircraft.
- Recruits Thugs to do your bidding, they are not stealthed but they are easily recruited to crack skulls.
Strangely, Iran builds a Nobles' Palace instead of a vizieralty.
