This is mostly for end game.
Anyway, go to war with some AI that has a lot of gold.
Take a city and kill his army to force out a peace a deal. Now, in the peace deal trade back the city you just took for a lump sum of gold. You can get ~9000g sometimes.
Also, sometimes there is a city that you can take but you can't really hold. You can do a flat peace deal or take the city and trade it for gold on the turn you take it.
Usually taking cities in the end of the game is pointless since they will be in revolt for too long. However, you can sometimes peace and trade them off for a lot of gold during the peace deal.
Don't ask "what do you think of the deal" just do the trade and see if they accept.
