Of course there's the jaguar warrior rush, but for something different...
1. Play as Carthage or France on an 80% pangea map at a low level (Cheiftain, Warlord, maybe Regent, I think Monarch possible for this strategy, I don't know about Emperor). I prefer Carthage for a coastal start. The smaller the map size, the better (tiny over small, small over standard, etc.)
2. Play with as few opponents as you can.
3. Make sure you have ivory.
4. Build your city and start on The Pyramids.
5. Research Mathematics first.
6. When you learn Maths, swap from The Pyramids to the Statue of Zeus.
7. After the Statue of Zeus, go out exploring with ancient cavalry.
8. Start attacking enemy cities, don't formally declare, just attack. I'd suggest having 2 ancient cavalry before you attack.
9. Once you're down to one tribe, surround the last remaining city with ancient cavalry.
10. Make peace with that tribe eventually, and sign a right of passage with that tribe so your ancient cavalry will stay in their borders and they can't move anywhere.
This actually comes as extremely detailed, so the strategy actually comes out a lot simpler than it may seem here.
