A nation is an aggregate of people united by common descent, history, culture, or language, usually inhabiting a particular country or territory, but not always. A state, on the other hand, is an aggregate of land with a sovereign government and laws, usually representing a particular nation or people, but not always.
So a micronation is simply a small nation, just as Monaco is a small nation, except that unlike Monaco, a micronation doesn't have full or exclusive control of a particular country or territory. This is the primary issue of statehood, the issue of full or exclusive control of a particular country or territory, while the issue of a micronation's lack of recognition by internationally-recognised states (UN members states or world governments) or intergovernmental organisations (major international organisations) is in fact the secondary issue of statehood. The existence of the de facto state of Somaliland, a Third World nation despite it is not recognised by any state, is proof that full or exclusive control of a particular country or territory, and not recognition by any world government, is the primary feature of any real state.
It should be noted that micronations are either real nations — made of real people united by common descent, history, culture, or language, although they don't necessarily inhabit the same particular country or territory — or they are simply not micronations. The claim of being a micronation does not constitute proof of a micronation's existence.
This website acts as a portal only to real micronations, ie small Fifth, Fourth, or Third World nations  whose existence we are fairly certain of at the present, and whose existence we can safely assume for the near future. This website shall not concern itself with extremely young or infantile micronations — Sixth World nations at best — or fictional states. While past media attention is deemed sufficient for a fictional micronation's inclusion within the Wikipedia, this portal shall seek greater evidence for a micronation's existence: recognised institutions, recognised standards, registered trademarks, real world influence over media and other foreign national institutions, etc.
Any listing of a micronation here does not imply endorsement, favour, or diplomatic relations with the people or government of the United Micronations Multi-Oceanic Archipelago (UMMOA). Respectful comments or suggestions for improvement are welcome.
