I made this

Allied Morocco day 1, started building spy network on Tlemcen and improved relations with the Ottomans. Shipped my army to the border with Tlemcen and dow as soon as I got a claim, called Morocco with a promise of land, claimed all the provinces as vital interest (so Morocco wont be mad when I give them no land) and took all the Tlemcen provinces that I had occupation on. While this war was going on Touggourt ate Mzab and was dowed by Tunis. got a claim on them, allied Ottomans, and dowed Touggourt. Their ally Fezzan abandoned them and I got full occupation. Vassalized them so I was in a defensive war against Tunis. Called my allies and took 100% worth of provinces from them. Meanwhile Aragon attacked Castille calling in France, they had only Brittany as an ally so I got in on the fun again calling Morocco, promising land and giving none, took all the castillian provinces needed for Andalusia except Jaen and took La Mancha for the gold mine. Dowed Portugal for the provinces needed from them since England would abandon them (at war with France) and took just those two provinces plus humiliate. Had unbalance research at this point so waited til I could embrace Renaissance with just deving a bit. Embraced it, dowed weakened Castille taking Jaen and two more provinces needed to release Leon. Dowed Portugal again just for the fun of it (no allies) took Lisbon and Evora. And here we are in 1490. I had to keep improving with France btw so they dont join a coalition. ATM a coalition would only consist of Tunis, Aragon, Castille and Portugal but it doesnt form because of my good friend the Turks.
