SNAP!

I have a thing that I want to fight against every faction. The Turks were being destroyed by the Mongols before I got to boot them off a few battlefields. So I bought 3 cities in Spain and gave them to the Turks. There they started a new empire, pissed off the Spanish, Portuguese and Moors before my forces came through and blitzed them all out of Iberia. Last seen of the Turks was a Papacy siege of Fes in which the English helped them out.

Similarly the Egyptians were getting squashed by the French. So financial assistance comes their way plus bribing French cities and giving them to Egyptians... 200 years later and Egypt is the only power in the Middle East other than the English. Unless you count the French in Damascus.
