The amount of people who take the Anglo-Moroccan alliance seriously is far too many.
Al-Mansur was a man with a very weak hand who played it very well to make himself appear strong. Flirting with fighting a war against Spain alongside England and having grand plans of a new world colony and an invasion of andalusia wasn't something he was actually going to do, it was a thing he said he was going to do in order to force Philip into agreeing a more favorable contract with the Moroccans, which he did. Al-mansur didn't have actually have the resources to do anything like that.
Of course it is impossible to have Morocco invade Spain or colonize, however, with the sugar industry he had the wealth and could kickstart a moroccan """industrial revolution""", ATL begin : had he been intelligent enough to designate an heir and guarantee the safety of the succession, said heir, with both the gold of the songhai, the trade with england, and a stable state, could manage to secure an effective alliance with england, and naturally, as all the thirds sultan of a dynasty, he would build a fleet (no joke, generally it was the third sultan of a dynasty (Ya'qub Al Mansur Almohad or Mohammed The Second Alaouite) who get interested in establishing a consequent naval force), now let's admit he does it (with some help from british obviously) he can now chase Spanish Navies across the Atlantic, and he has a huge pool of sailors; the Andalusian expulsed and hateful towards the spanish. However, he quickly withdrew his decision, the moors are rebellious and some of them established themselves in the new world, founding their emirate there and working for the Re-reconquista from there, they obviously are better neighbours to the local than the intolerant castillians, and so their missionaries are more effective (I will leave it here, i will return in a few decades). Back to Morocco now, by this time we should be somewhere in the 1650's ? Our Sultan now is now something like 60 years, (wich might sound a lot, but wouldn't be that surprising for moroccan standards), and the anglo-moroccan alliance is nearly 70 years old, by this time I think that English presence in the moroccan court would begin to influence the local "nobility", and while the merchants guilds of Tangiers, Rabat-Salé and Al Jadida seeks out ways of joining the international trades, inspired by English traders and start building light ships, the corporations of Fez, Marrakech and Meknès begin to structure themselves into manufactures in order to regain their privilegias, lost when Al Mansur dissipated their economic influence with granting the sugar farms to religious orders, same goes for the tribes who finally after 6 centuries, settle down for good, and aside frim the lifestock, start cultivating grain. All this economical turmoil ( wich is possible only because the sultan I chose was a scholar as his father but not a dreamer, he will not claim the Caliphate, preferring to keep godd relations with the ottoman Caliphe ), will have three major consequences :
-The Jews of Morocco will probably establish themselves as the financial corp of the country, and thus they will start to form proto-banks (interest are banned in islam), and to preserve their own interests, will participate into the stabilization of the monetary situation, and the democratisation of the money.
-The reintroduction and massive use of the wheel, first by the corporations and merchants guilds (because of the already existing roads), then by the settling tribes, to keep use of their horses and to transport the harvest into the cities. Thus, trails will begin to appear, connecting coast, imperial cities and plains.
-The third consequence is directly connected to the second, with trails and eventually roads making their way out, it will become an obligation to secure those pathways, and so our Sultan will have to do two things : Either create police force (wich i found highly implausible, at this level, each component of the moroccan society is heavily isolated and the country is in a transition phase, sedentarisation od the nomadic tribes and immigration are changing the forces balance, and a national economy is just starting, we are still far from a national identity and a centralised government, and if you gave to much power to a general (and giving complete control of the roads is indeed too much) you can very quickly find yourself with a revolution) or go with a pacification plan, wich i choose.
Now for the serious business : Tafilalet and the south. It's been roughly 50 years since the contact between the Sultanate of Morocco and the Songhai Empire has been consistent, and Timbuktu and Gao are now a moroccan cities, and thus the government is no more extracting goods from these areas, but developping them. The trans-saharian route is more dynamic in this TL than OTL, because of the Moroccan fleet who are harrassing portuguese and spanish ships, hiwever unlike 5 decades ago, the main comoonent of this navy is arabo-berber and not andalusi. Speaking of them, 40 years after their secession, they send an ambassador with gold and gifts apologizing to the Sultan, and recognising his authority, they ask for him to send settlers in the New World, they are in desperate need for people and slaves, in exchange they will pay the sultan a tribute of gold. At first suspiscious, the sultan accept, too eager to receive the gold and have a base of operation in the Americas, he send prisoners, christian war-prisoners, slaves, various tribal people, and even 30 burghers that accepted to emigrate in Jazirat Gharnata.
As Abd Al Malik Al Mutawakkil The Second, switch off his candle, he goes after the Heavenly Companion, entering history alongside his Father, and letting his son in charge of a stable and wealthy country, with a great ally and a good navy. In this sixty years, we successfully managed to stabilise morocco, by eleminating the worst threat the tribes, we gave him a good economical basis and a protection from financial crisis, alongside a naval improvement, our next ruler will take the throne in 1666, the date where the alaouites rose in OTL, but in this one it will be the date, where the Raddi'y Arrûm will enter.
