I basically beat this already. Had a save where victory was near certain (but would've taken another 200 turns to actually win) that was lost from reinstalling. I played as Hatty and chariot rushed saladin, cyrus, and asoka. It's kinda a luck-based start - sometimes saladin would tech hunter-archery immediately and I would restart while cyrus would start with hunting and not tech archery for 40 turns. After taking mecca I immediately started building pyramid there, plan was to run representation+mercantilism+statue of liberty for science, since you'll have insane city maintenance until state property, at which point you should have basically won the game and can then steamroll all ais. I filled in the land from egypt to india and then into turkey a little bit, and then just defended while I teched to infantry. It's really hard to push into europe head on so I would build a spare army every 20 turns or so and ship them to greece->rome->spain->england and finally landed in france. I left mansa alive for a very long time, he's not a big threat at all, idk if it's worth it to kill him fast and start developing all of africa asap, or to just focus on your already good cities and conquer europe first.
