Why unify a country?
Unifying people to make a new nation can help solve conflicts and please those involved. Creating your own country can make sure your voice is heard, that the government is functioning in a way that is considered fair and efficient, and so on. Lets take Italy for example. The people of Italy wanted to unify because they were tired of constantly being under French control. So, why not create your own country if you are having these types of issues?
