OK, I checked the save briefly. There is good news and there is bad news.
The good news is you won't be getting a diplomatic hit from your war with saladin. The bad news is Saladin WHEOOHRN. He is Friendly with Ragnar and Justinian. However there is this non-Islamic country to his Southwest that is the 2nd weakest civ in the game.
Stop building Trebs sis. you're not invading anyone. you, my good sir, are Jihad-bait. You need Pikes and Muskets. Pikes for the inevitable onslaught of mounted units. Muskets to protect your cities and Pikes in the field. I would definately consider switching to Military Science. Saladin is going to come over the border with Cuiriassiars. With shock they are a even match for c2/formation pikes. And if you try to counter attack his Sod the pikes get taken out by protective x-bows and maces. You can produce C2/Formation grens from all your cities. When attacking they have a slight edge over Cursedhorses if they have pinch. And pwn them if they don't. The majority of his CA's and WE in Kufah are either flanking2 or Combat2. which means when they get promoted your grens will slaughter them. Low production cities can produce a few barrage2 cats to soften the stack. With Aksum producing level4 knights under theo/vassalage you can then attack his stacks to eliminate the siege units. Consider saving a promotion for pinch since sal will probably be sending musckets soon as well.
Build/whip a freaking library in Minoan. A library would have been much much better than a harbor. The harbor increased your commerce in that city by exactly 1.5

With a library you can run scientists and work the water tiles while you WHIP units. You're in slavery and HR but have no whip anger in any of your cities. Imagine all those whipable citzens representing people with Airconditioning.
Run every possible specialist possible in baylon. When you get a GP use them for a GA to switch to Islam and theo/caste. While in the GA, run max scientists and an engineer in baylon to gobble GPP. Switch back to slavery right before the GA ends.
while in the GA, mover all your workers in Minoan to water tiles for the hammer and commerce boost. Whip a grocer and market there as well. Even after the GA stay on water tiles until you have the population you need to work all the water tiles plus the workshops and incense. Or until you can run a pile of specialists while stil working all the coastal tiles.
During the imminent war with saladin try and grab one of his southern border cities in case you can offer it for peace. Hopefully, once you get peace the islam/theo diplomatic bonus will get saladin up to friendly so you can turn your attention elsewhere(as in darius)
