Government

After you make the informal name, you must come up with a basic government to complete the formal part of your name, if you would wish to expand your government afterwards i would suggest you do that very last, right before you formally declare independence.  Your government can be as simple or complex as you wish.

Note: many micronations use a monarchy for their government, many more are republics, but your government can be completely different. Take my micronation, The McKtonion Empire, for example: 

It has no parties (all people elected in are independent) and has a 3 party system of judicial, legislative, and executive branches. However while this model may look similar to the model of the US government, it is extremely different. First off the executive branch is made up of 2 people, The Emperor (current incumbent: McKay Roundy) and the Prime Minister (current incumbent: Zachary Weber), this empire does not just have the emperor as a figure head, nope he is the co-head of state, each has their own duties and each has their own powers, the Emperor stays in for life, unless an Imperial Election is called by the prime minister or 2/3 of the people. An Imperial Election consists of the current Emperor and the Prime Minister. After the Emperor dies an Imperial Election is always called, this time consisting of the Current Prime Minister, the First born of the last Emperor, and the Head of the Imperial Senate.
