Microstate
sovereign state having a very small population or very small land area / From Wikipedia, the free encyclopedia
A microstate[1] or ministate is a country that is very small in size, or has very little amounts of people living in it. Usually, both cases are true. However, there are no set definitions of the terms "state" and "very small".[2]
Some examples that are usually called microstates include Andorra, Bahamas, Comoros, Djibouti, Equatorial Guinea, Fiji, Guyana, Iceland, Kiribati, Liechtenstein, Monaco, Nauru, Palau, San Marino, Tuvalu, Vanuatu and Western Sahara. The smallest state in the world is Sealand, in the U.K.
In addition, Greenland has been included here for its possible wishes or chances of independence. Bougainville is also there for the same reason.
