It's not so much as Morocco being powerful (though it is a very prosperous independent state with strong ties to the USA), but rather the rest of North Africa decided they had had enough of being ruled from Istambul so once the die-hard Ottomans were defeated by the Moroccans and their Human League allies the North African peoples called for being ruled by the Moroccan Sultan. It's going to be quite the process for both Morocco and North Africa.
Honestly, at this point it's a Moroccan
Empire. But at least one where the non-Moroccan member countries are glad to be part of it.
It's set up to be one hell of a prosperous state: lots of really good ports, oil, the Suez Canal, etc. If the sultan has any foresight at all, he'll get behind several measures to develop his empire. I'd suggest:
A proclamation of religious tolerance, while retaining Islam's primary place
Measures to encourage the prosperity of trade through his major ports, making his empire a hub like OTL Singapore
MASSIVE investment in a railway system connecting the coastal cities with resource nodes in the interior
founding of world-class universities ( and upgrades to those already in existence) to gin up the idea economy ( OTL, this is a
HUGE part of the US's power/prosperity)
a first rate navy ( having all that coastline makes it necessary to be taken seriously and protect the attempt to make trade a primary concern of the state)
As I recall, Morocco was the very first country OTL to recognize the US, right after the Declaration of Independence. Is this true ITTL?
