They also have decent military bonuses: +10% morale and +10% manpower, meaning their armies will be of help when you use the 'colonial war' type of DoW. They're altaïc culture and sunni, thus you can feed them all Central Asia, they'll manage without too much rebels (they also have -1 unrest in their ideas). They have great National Ideas to bring more trade: caravan power, trade efficiency, provincial trade power and domestic trade power. They're chinese tech and non-horde, thus they're eligible to becoming protectorate. Indeed, if you don't want to blob all of Central Asia to Mongolia, but still want the trade from it, they're the best candidate: Not as vassal but as protectorate, I'd like to suggest Yarkand. So if you are going for massive conquest its best to just spend your admin points elsewhere and leave the Maghreb as a vassal. The only thing one would really want in north africa is the important center of trade provinces and perhaps some of the coastline provinces to increase naval forcelimit. The north african land is fairly low development so not worth making into states, you can easily suck all the trade away from it too so you don't need hte land for trade power. In fact, Morocco, Tunis, Tlemcen are all good candidates for permanent vassals, specifically because they have that increased coring cost. Maghreb nations are not the worst.the small ones in the deep desert are bad but Morocco or Tunis are pretty good for vassal and reconquest. Ottos is really good vassal because it has lots of cores and great military benefits. If a big nation like France, Castile, England dies or gets small you can grab them as vassal and go reconquest. Yes but the piont of the thread is when and where is it worth it.
