Summarize:

You don't have to buy any land for a nation, you just have to claim it. It can be a room in your home, your backyard, your whole property, or something public, such as a park or an empty lot. You can also claim an uninhabited island or a deserted section of the forest. Be sure to find out and follow the laws concerning claiming land in your area. Some micronation creators choose to live on a ship off the coast of a sovereign nation, as well. Decide on a type of government, such as a republic, monarchy, or dictatorship. You could also create your own political party. Enforce this government and ask other citizens to become officials. You can choose to be the leader, or you can elect someone else to be the leader of your new government. You can create a constitution or write laws for your micronation. For example, you can choose to ban certain items in your country, extract fees for entering your nation, or have your citizens pay taxes. Micronations are free to create whatever laws or restrictions they wish! Every nation needs a strong economy to succeed. You can choose to use the currency of your parent nation, or create your own! You can order custom coins and currency online, if you decide to create your own. Create and develop industries and discuss trade options and other economic factors, like if you’ll have a stock market, as well. You can contact other micronations' leaders to develop diplomatic relationships and, furthermore, ratify an international treaty or alliance. Your friends or relatives can be ambassadors of your country. Remember to use official and formal language in your documents and at diplomatic meetings, especially if you’re communicating with established governments. You can make your own stamps, assuming you’d have your own postal service to deliver mail, or go online to order custom stamps that your parent government will recognize. Passports are another item your citizens may need if they plan to leave or reenter the land that’s been designated for your micronation. Enlist your citizens to help you design and manufacture these essentials. If you’re aiming to become a sovereign nation, you’ll need housing, schools, offices, farms, stores, banks, industries, and more. You could also add a park, memorial, small museum, or gallery to your micronation’s territory. For example, you can fill a memorial room with important documents, artifacts, paintings, and photos of your micronation's history.
Claim territory for your nation. Construct a government for your nation. Create laws and restrictions. Build an economy. Develop diplomatic relationships. Issue passports and stamps. Add attractions to your territory.
