Let's start with the explanation of the basic belief of nationalism which is nothing but people who belong to a single nationality or ancestry should come and live under the same government. There are three types of the nationalist movement and they are unification, separation and state-building. As the word unification defines it is nothing but merging the politically divided land but they are culturally same. Separation is defined as culturally distinct groups resist to be a part of a state. State-building is a culturally distinct group forming into a state.
