Hygro: you don't have to sacrifice a good city to do it. Build your capital, and build a second city with just one tile between. Keep your capital pumping out settlers and make it stay small, 1/3 or 2/4. Your second city might produce some military, but fairly soon it prebuilds the forbidden palace.
Attack your nearest neighbour. Take their capital, and some cities around, perhaps setting around it too. Grow their capital to be your biggest city with the most other cities around. Then disband your capital which has done little but produce settlers and workers, when it's size 1 or 2. It has no improvements other than the palace. Your capital will jump to the capital you captured. You're losing a small town out of it, that's all.
Oh and about capitals moving in real life, when the Commonwealth of Australia (my country) was formed out of a collection of British colonies, the two biggest colonies, New South Wales and Victoria, both wanted their capital to be the capital of Australia. There was bickering and it couldn't be decided. In the end it had to be put in the Constitution that a new capital would be built exactly half way between Sydney and Melbourne
Melbourne was the capital for the first twenty-something years though, before it moved to Canberra.
-Sirp.
