At the end of the last round I was gearing up for war. I decided that I wanted the continent all to myself, which meant Evil HC and Not-Particularly-Evil Sully had to go. And they were going in that order even though Sully was closer, because Sully had teched Gunpowder and I didn't really want to deal with Janissaries right now. Plus, Sully could probably convince HC to join in against me, but the opposite wouldn't happen.
HC had a standard Medieval army: Longbows and Pike everywhere, a handful of Knights & Maces, some Cats/Trebs, and some outdated melee units (axe/sword). Meanwhile I was rolling with 2 stacks of 8 Cannon each, some Rifles, CR-II Maces which would be upgraded after reaching CR-III, a couple Cavalry, a half-dozen or so Camel Archers to be upgraded as needed, and a couple War Elephants & Pikes for dealing with enemy mounted units. I also brought along some spies in case I wanted to incite revolt to take down cultural defense immediately and one stack had my Woodsy-3 Warrior as a healer. I aimed to sweep through the less-mature Western side of the empire, then work around the coast into his core. After that I would take a small contingent on Galleons to dispatch his 4 awful tundra-island-expansions while the rest of the troops healed up and readied for the Ottomans.
For the most part, that worked well. I did have a bit of a scare when HC ignored my newly-conquered cities and took his counter-attack stack of knights, cats, and assorted melee/archers towards my borders. But with suicide catapults and the loss of a couple Riflemen his stack was utterly destroyed by my border patrols and there was never another threat. Within 25 turns, HC had been evicted from the Arabian Continent and reduced to his island retreats. I thought about Capitulation here, but that would leave some Motherland unhappiness and, frankly, I just didn't like him. Since it wouldn't take much more effort to kill him completely, I chose instead to capture the 4 cities and spawn them off into a friendlier colony. So, after a few more turns, and some descriptive city-renaming, Tokugawa enters the world:
Then it was time to take on the Ottomans. At this point I start thinking about Victory Conditions. Conquest/Domination are out because I just don't want to deal with invading the other continent, culture is doable but I hadn't really specialized for it and so it will take a looooong time since my #3 city is just over 10,000 right now and Epic Legendary is 75,000. So I was down to Space or a diplo win. That's when the idea of AP diplo struck me. Only one of the 4 Western Civs had any AP religion but all of my cities (and Sully's) were Buddhist so I had plenty of votes. From a strategic standpoint, the best approach would have been to beat Sully down to the point where I'd be just under the limit, take his capitulation, and spread Buddhism to Toku to give me enough votes to go over the top. But.... I really wanted to destroy Sully. I had set a goal of owning this continent, and damn the victory conditions I was going to do it! I'd deal with the consequences later.
I had wanted some extra time to make sure everyone was fully healed and reinforced, but the Ottos started teching Rifling and I just couldn't let that happen. Sending my Cannon/Rifle/Cavalry army against Janissary/Cuirassier/Mace/Longbow was fine, but if he got rifles of his own, that was going to complicate matters greatly. So, with Sully 8 turns from Rifling, I made my move. Between the loss of his cities (including the Buddhist shrine fairly early) and a desperation civics change his tech slowed to the point where I didn't see a rifle until the final battle. And by then it just didn't matter. At turn 401 (1782 AD), "continental unification" was complete and it was time to revisit the victory conditions:
As you can see from the screen, I had spread Buddhism to a single English, Indian, and Carthaginian city as well as to Tokugawa's cities in preparation for an AP victory run. But with the capture of the Ottoman cities I have too many votes (868 with only 799 required.) So at this point, I stagnate all of my cities to keep my vote count from increasing (strategically, I should have actually starved them just like I probably should have razed some of the Inca/Otto cities, but that just "felt wrong" so I wasn't going to go that far.) With Toku voting for me, I just had to push it to the point where my own votes were just under the limit and I'd get the win. Of course, on Epic the votes only come every 13 turns so there are some timing considerations too.
Toku inadverntently tried to thwart my plans when he went and switched to Buddhism after it had been spread to all his cities. That meant he'd be declared a second candidate and would no longer vote for me. Oops.

However, I was able to get back on track by switching to FR myself, bribing him to do the same, and then switching back after 5 turns. I also put spies down in his territory in case I needed to force him away from it again later but he happily stayed in FR the rest of the game. I hadn't gotten enough spread by the next vote, but when the vote after that came around, I had put myself in the winning position. I was at 866 votes with a requirement of 861, but there were 3 Missionaries hanging out in Indian 1-religion cities ready to go. Spreading to the 12-population Lahore upped the requirement to 870 and with Toku's votes there was plenty of leeway for population growth changes so we were ready for the final vote:
Which means:
And yes, I went back and retook that victory screenshot with the proper name since I had played this whole thing calling myself NCIV Saladin instead of NCXIV Saladin.

This kind of AP victory is a little cheap, but I sometimes get bored in the late game with a huge empire and the religious nature of the win fits the leader so that's the route I chose.
Final State of the Arabian Empire:
