Domination victory in 1998AD, and I barely reached modern times too!
It was a constant cat-and-mouse where I would be defending heavily but always trying to make a few decisive hits on the AI territory. From my early spoiler I had 2 Chinese cities in the west, well these fell soon after 500AD and the baddies started knocking on my front door again.
War elephants were my bread-and-butter for border defense most of the game as they could kill the stupid mounted units that kept pouring in.
One funny fact, I built the Great Lighthouse in Tenochtitlan without the knowledge of sailing, I also managed to build the Hanging Gardens in that city, which let me get a few gpp's.
I "rushed" for feudalism (1530AD!) with a plan to retake a few western cities on hills in the centre of the continent and fill them up with CG LBows to try to release the pressure on my homelands again. It worked pretty well. I kept harrasing poorly guarded cities where I could, but mostly was concentrating on getting some research done before attacking in earnest. I was the first to get Grenadiers and I started cranking these out for my real offensive push. I backed these up with cannons as I was meeting gunpowder units in the enemy cities. I wanted to get a conquest victory to avenge all of those people who got an English archer in the first 20 turns.
In my first spoiler Qin and Monty got it early, and Liz was banished to the tundra wastelands fairly early on aswell.
So...
Slowly but surely... Khaan (~1850AD), Bismark(~1907AD), Isabella (~1930AD), Toku (~1960AD) and Louis (~1967AD). My hands and wrists were cramping up by the end of the game with all of those mundane troop movements

Louis was actually the first I eliminated properly because all the others had 1 tile islands. I had delayed attacking these little islands as there was still about 15 or so galleys marauding around the shores so I had put-off building any ships. The game was finished really once the last continental city fell but I wanted to hold underneath the dom limit and get a few more techs and pop to boost my score. I was hovering very very close to the dom limit and a border pop put me to 60.15% land in 1998AD just as I was getting ready to kill the final one tile cities with galleons and ironclads.
One low point was having 4 catapults and 5 conquistador's land by galleon on my poorly defended eastern flank to capture Tenochtitlan, one of my cornerstone cities. It was my mistake of thinking that this was the furthest from any war position, I had been pretty good at seeing the galleys coming around the shoreline, but the galleons plopped in from the great fog of black beyond the coastline.
I suppose that episode was somewhat historically accurate though! (But did the real aztecs have grenades and elephants to repel them?)
A few final comments:
The tech pace was terrible, from my turn log I got agriculture in 1400AD, sailing in 1857AD, alphabet in 1877AD and polytheism in 1912AD! heh
Units killed : 1616 (293 catapults, 266 horse archers!!)
