I finished with an Atomic-era Diplo victory on turn 255. It was a UNANIMOUS VICTORY -- every single world leader vote was cast in my name.
Spoiler :
I took out France, Japan, and Portugal with Crossbows. Got Gatlings in time for war with Siam, and those were also enough to get Attila, especially with a ton of free units from Militaristic CSes. Gandhi built the Great Wall, so I waited for Artillery and got him with a secondary army. Reduced Attila to almost nothing, then liberated Brazil and simultaneously eliminated Attila the turn before the final vote. Brazil voted for me.
I delayed Printing Press a lot and was able to get into the Atomic Era before the second World Congress session. Had to wait 15 turns for World Leader vote -- not too bad. Went to Atomic through the bottom part of the tech tree, which I think is cheaper, beakers-wise, and is also kind of a no-brainer if you want Artillery.
I have a somewhat longer writeup with a bunch of pictures linked below. I don't like confining things to external links and would rather copy-paste it directly here, but I have trouble with image sizing/formatting on this forum:
