Mamluks now have their titular unique Government type: The
Mamluk Government, where the ruling class' culture is of great importance. The Mamluks do not get heirs or consorts but always get a new Sultan on Monarch death. The Mamluks nation will decide if they would like to be governed by a Sultan from their own cultures' lands or take a slave ruler from further afield. Historically and in our setup, they will be able to bring in Circassian rulers, who are seen to have high legitimacy over ruling the nation, but you can elect to choose a ruler from lands of other cultures within your nation. While these Sultans will have lower legitimacy, scaling with the amount of your culture lands they have, they will have another advantage in using their Cultural Interactions.
Each year the Mamluk Government will gain 3+ruler ADM/DIP/MIL stat for each of their cultural interactions which can be used as follows:
- ADM Action: Promote [ruler culture] in Government
- Gain -5% all power cost for 1 years.
- DIP Action: Sell off [ruler culture] slaves
- Gain ( Development of ruler’s culture * 2 *current Age ) ducats
- MIL action: Recruit from [ruler culture] lands
- Gain ( Development of ruler’s culture land * 50 * current Age ) manpower
So while a home-grown Sultan may start with low legitimacy, you may prefer them over a more stable alternative to get more out of your interactions. Additionally, spreading and conquering certain cultures may be of more interest for the Mamluks.
Additionally, the Mamluk Government itself will give +2 to all Sultans' ADM stat, and allow extra cultures to be promoted, depending on the Government Rank of the nation. Promoting cultures is also 50% cheaper for a nation with Mamluk Government. Now I say "a nation with Mamluk Government" instead of just "The Mamluks" because an Iqta nation who holds Cairo while the Mamluks have been wiped out can adopt the Government for themselves.
