The term ''unification'', in a political sense, refers to the unification, or rather merging, of two or more countries into one country. This can be performed by countries that have been divided (for example West Germany and East Germany), countries that have mutual interest to function as one country (for example Yugoslavia), or countries that have the same ethic and cultural background but haven't been functioning as one country (for example Italy).
This process of Unification can be functioned between those countries that have been divided for a long period of time such west and east Germany which was divide after the world war two, countries that have same wants to function as one country such as Yugoslavia, or those countries which share countries mutual culture and ethnic background but haven't been functioning as one country such as Italy.
