The smallest capital in the world is Melekeok on Palau. With only 520 inhabitants it is even smaller than the Vatican. Vatican City is in fact only the second smallest capital in the world despite it being the smallest country with just over 900 people living there.
If you consider the Falkland Islands a country despite it technically being a British Overseas Territory its capital Stanley would be the third smallest capital. It has just over 2000 inhabitants.
