OK, so all people who have played Portvcale know how the Moors generally face about 3 enemies, later 4. I found a way to conquer all 4, and beyond.
So, First, I prepared to kill each enemy 1 at a time. First, I crushed Portugal. Then, I conquered Aragon. Castille and Leon still lived, until I killed them as well, and Navvare. Now I planned to invade France, but something amazing happened. I was able to buy all of the French cities, therefore making them: "The Independent Christian Kingdom of Paris". I allied with England.
Germany attacked me. I drove them out of half of Germany. However, thats where I stopped. See, my empire was huge, but France attacked me for no reason, and Denmark, and England, and the Italian City States.
End.
