The requirements are: -Own three cities in the Maghreb and conquer two cities in Iberia and West Africa by 1200 AD. -Build La Mezquita and have a total of four great engineers, prophets, and scientists in Cordoba by 1300 AD. -Acquire 3000 gold through piracy by 1650 AD. Here's what I figured out so far: -On the first turn, switch to Citizenship and (I think that's the one that gives extra production on pastures) Manorialism. -Focus Cordoba on Great People. Other cities won't build them in time, not even Marrakech. -Three things that have to be whipped as soon as possible in Cordoba are a Mosque, La Mezquita, and a Library, in that order. A Church can go instead of the Library in case Catholicism spreads to Cordoba. -First, beeline to Gunpowder, then to Exploration. Arab and Byzantium will be your two main trading partners. -The first settler should found Tunis, to secure the Stone resource there. Build a second settler to found Wahran or Al-Jazair. -Right after finishing La Mezquita, switch to Monasticism. -After that, keep a population of five or more, and build or whip a Forge and a Library, and work all Priest, Scientist and Engineer slots as possible. -Build as many Siege weapons in all other cities before you secure at least one Iron and one Horse resources. Then, two or three Lancers should be enough to take over Mali, and the rest should be used to help conquer Iberia. Both armies should be ready before 1100 AD. -Depending on game speed, Portugal may not be able to be declared war on before 1200 AD, so you will have to conquer two Spanish cities. The obvious first choice is Madrid. Barcelona is better than Santiago, as it has one silver resource. -After researching both Gunpowder and Exploration, build as many Corsairs as you can. Focus them on the Mediterranean, Africa and Asia. If Portugal is still alive, besiege Lisboa. If any European civ builds Frigates, they're doomed, so besiege Europe as much as you can before they arrive.
